An inductor component comprising an element body; a helically wound coil disposed in the element body; and an external electrode disposed in the element body and electrically connected to the coil. The element body includes a plurality of insulating layers and a mark layer constituting a portion of an outer surface of the element body, and a K abundance ratio (atom %) in the mark layer is higher than a K abundance ratio (atom %) in the insulating layers.

Inductor component

An inductor component comprising an element body; and a coil disposed within the element body and wound along an axial direction. In an inner diameter of the coil, the inner diameter of the coil at both end portions in the axial direction is greater than the inner diameter of the coil at a central portion in the axial direction.

Inductor component and electronic component

An inductor component includes an element body. The element body has a mounting surface and a top surface that are parallel to each other, first and second parallel end surfaces, and first and second parallel side surfaces. An inductor wiring is disposed inside the element body. A first lead-out electrode is connected to a first end of the inductor wiring in an extension direction of the inductor wiring. A second lead-out electrode is connected to a second end of the inductor wiring in the extension direction of the inductor wiring. A lower surface of the first lead-out electrode and a lower surface of the second lead-out electrode are exposed from the mounting surface of the element body. The first lead-out electrode has a substantially quadrangular columnar shape that extends in a height direction. The first lead-out electrode is exposed from the first end surface and the first side surface.

An inductor component includes an element assembly formed of an insulator material and an inner electrode arranged in the element assembly. The insulator material contains a base material formed of an amorphous material containing B, Si, O, and K and a crystalline filler and includes a filler-poor glass portion in a region along the inner electrode. The content of the crystalline filler in the filler-poor glass portion is lower than the content of the crystalline filler in the element assembly excluding the filler-poor glass portion.

An inductor component includes a component body having a mounting surface and a top surface and provided therein with a spiral inductor wiring line advancing in the extending direction of a winding center axis. The inductor wiring line is connected to a first external electrode at a first end, and connected to a second external electrode at a second end. The component body includes: a first inclined surface connected to a first end of the mounting surface on a first side in a length direction and inclined toward the top surface as separating from the first end; and a second inclined surface connected to a second end of the mounting surface on a second side in the length direction and inclined toward the top surface as separating from the second end. The winding center axis extends in a direction parallel to the mounting surface and perpendicular to the length direction.

Inductor component and inductor component mounting substrate

An electronic component includes a body having a side surface, coil conductor layers wound along main surfaces parallel to the side surface, and capacitor conductor layers each having a substantially plate-like shape parallel to the side surface. The coil conductor layers and the capacitor conductor layers are arranged in a widthwise direction perpendicular to the side surface. The capacitor conductor layers include first and second capacitor conductor layers adjacent to each other in the widthwise direction. The coil conductor layers include a first coil conductor layer that is in the same layer as the first capacitor conductor layer and a second coil conductor layer that is in the same layer as the second capacitor conductor layer. The shortest distance between the first coil conductor layer and the first capacitor conductor layer is larger than the shortest distance between the second coil conductor layer and the second capacitor conductor layer.

Electronic component

An electronic component includes a single-layer glass plate, an outer-surface conductor that is disposed above an outer surface of the single-layer glass plate and that is at least a part of an electrical element, and a terminal electrode that is a terminal of the electrical element. The terminal electrode is disposed above the outer surface of the single-layer glass plate and being electrically connected to the outer-surface conductor.

Electronic component, electronic-component mounting board, and electronic-component manufacturing method

A multilayer resonant circuit component includes a multilayer body in which first electrode layers, which are provided with both coil patterns and capacitor patterns that constitute an LC circuit, are stacked with first insulator layers interposed therebetween. The multilayer body further includes, stacked together with a second insulator layer, at least one of the following: one or more second electrode layers that each include only a capacitor pattern; and a third electrode layer that includes only a coil pattern.

Multilayer resonant circuit component, packaged multilayer resonant circuit component, and multilayer resonant circuit component manufacturing method

An inductor component having an element body includes two end surfaces opposite to each other and a bottom surface connected between the two end surfaces. A coil is provided in the element body and wound helically. Two external electrodes are provided in the element body and electrically connected to the coil. One of the external electrodes is formed over one of the end surfaces and the bottom surface while the other external electrode is formed over the other of the end surfaces and the bottom surface. The coil is formed such that an axial direction thereof is along the two end surfaces and the bottom surface. The coil includes a coil wiring wound along a plane orthogonal to the axial direction, and the aspect ratio of the coil wiring is 1.0 or more and less than 8.0.
