Photosensitive insulating paste and electronic component

A multilayer inductor component includes an element body that is an insulator and a coil in which a plurality of coil conductor layers that extend along planes in the element body are electrically connected to each other. Also, each of the coil conductor layers includes metal part and glass part, and the glass part include internal glass portion that is entirely included in the metal part.

Multilayer inductor component and method for manufacturing multilayer inductor component

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 is mounted on a circuit board such that a mounting surface of an element body to which a first outer electrode and a second outer electrode are exposed is directed toward the circuit board. A coil is formed of a spiral coil in which a plurality of coil conductor layers arranged in a direction perpendicular to a first side surface and a second side surface orthogonal to the mounting surface are connected in series. Then, an intermediate point between a lowest point closest to the mounting surface and an uppermost point farthest from the mounting surface in an inner circumference of the coil is offset from the center of the element body in a direction perpendicular to the mounting surface toward the opposite side to the mounting surface.

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.
