Document Type and Number:
WIPO Patent Application WO/2024/095568
Kind Code:
A1
Abstract:
Provided is an inductor component that can increase inductance acquisition efficiency. The inductor component is provided with: a prime field including a first main surface and a second main surface which face each other; a coil which is provided to the prime field and which is helically wound along the axis; and a first external electrode and a second external electrode which are provided to the prime field and which are electrically connected to the coil. The axis of the coil is disposed in parallel with the first main surface. The coil is provided at the first main surface side relative to the axis, and includes: a plurality of first coil wiring portions which are arranged along the axis on a plane parallel with the first main surface; a plurality of second coil wiring portions which are provided at the second main surface side relative to the axis and which are arranged along the axis on a plane parallel with the second main surface; a plurality of first through-wiring portions which extend from the first coil wiring portions to the second coil wiring portions and which are arranged along the axis; and a plurality of second through-wiring portions which extend from the first coil wiring portions to the second coil wiring portions and which are provided at a side opposite to the first through-wiring portions across the axis and are arranged along the axis. The first coil wiring portions, the first through-wiring portions, the second coil wiring portions, and the second through-wiring portions form at least a portion of the helical shape by being connected in the stated order. At least one of two opposite-end first coil wiring portions, which are positioned at opposite ends in the axial direction from among the plurality of first coil wiring portions, and two opposite-end second coil wiring portions, which are positioned at opposite ends in the axial direction from among the plurality of second coil wiring portions, is a wide coil wiring portion. The maximum width of the wide coil wiring portion in the axial direction is wider than the maximum width, in the axial direction, of at least one coil wiring portion of inner side coil wiring portions from among the plurality of first coil wiring portions and the plurality of second coil wiring portions excluding the opposite-end first coil wiring portions and the opposite-end second coil wiring portions.
