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.

Inductor component

A loop conductor layer of the coil conductor has a lower side portion, lateral side portions, oblique side portions, and an upper side portion. The lower side portion has a length shorter than a gap between outer terminal electrodes, and is positioned within a range of the gap.

Lamination inductor

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

The via hole conductor connecting the first inductor conductor layer and the second inductor conductor layer is provided closer to the first outer electrode than the second outer electrode, and when viewed in plan view from a normal direction of the first end surface, does not overlap with the first outer electrode.

Electronic component

An inductor component has an element body defined by a length, a height, and a width, a coil disposed in the element body and helically wound in the width direction, and first and second external electrodes disposed in the element body and electrically connected to the coil. The coil includes a plurality of coil conductor layers arranged side by side in the width direction. The plurality of coil conductor layers is each wound in parallel with a plane including the length direction and the height direction. At least one of the coil conductor layers has a shortest distance of 140 &#x3bc;m or less in at least one of the length and height directions between an inner circumferential surface of the coil conductor layer and an outer surface of the element body opposite to this inner circumferential surface.

The electronic component includes a substantially rectangular parallelepiped multilayer body formed by laminating a plurality of insulation layers, a capacitor including a plurality of capacitor conductor layers provided on the insulation layers, and a substantially spiral-shaped inductor including one or more inductor conductor layers provided on the insulation layers and having a center axis extending along the lamination direction. A mounting surface of the multilayer body is a surface of the multilayer body located on the end of one side of a first orthogonal direction orthogonal to the lamination direction. The inductor conductor layer and the capacitor conductor layer are provided on the first insulation layer. On the first insulation layer, an end portion of the capacitor conductor layer on the one side of the first orthogonal direction are closer to the mounting surface than an end portion of the inductor conductor layer on the one side of the first orthogonal direction.

An electronic component having: a laminate formed by laminating a plurality of insulator layers; and a coil consisting of linear coil conductor layers that are laminated along with the insulator layers, the coil having a spiral form or a helical form that windingly extends in a direction of lamination.

The electronic component includes a multilayer body having plural insulating layers stacked in a staking direction. Outer electrodes are provided on facing lateral sides of the multilayer body and extend in the stacking direction. Coil conductors are stacked together with the insulating layers to form a coil. The thickness in the stacking direction of at least one of the coil conductors that is directly connected to one of the outer electrodes is smaller than that of the coil conductors that are not directly connected to any of the outer electrodes.

A multilayer body is formed by laminating multiple insulating layers. External electrodes are provided on the opposed side surfaces of the multilayer body and extend in the z axis direction. Coil conductors are laminated together with the insulating layers and form a coil. Coil conductors other than coil conductors connected to the external electrodes are made up of pairs of adjacent coil conductors having an identical shape, and coil conductors forming each pair are connected in parallel to each other. None of the coil conductors connected to the external electrodes is connected in parallel to coil conductors with an identical shape.
