Title:
INDUCTOR COMPONENT
Document Type and Number:
WIPO Patent Application WO/2024/095565
Kind Code:
A1
Abstract:
Provided is an inductor component enabling higher efficiency of inductance acquisition. This inductor component comprises: an element including a first principal surface and second principal surface that face one another; a coil that is provided to the element and is wound helically along an axis; and a first external electrode and a second external electrode that are provided to the element and are electrically connected to the coil. The axis of the coil is arranged in parallel to the first principal surface. The coil includes: a plurality of first coil wirings that are provided to a first principal surface side with respect to the axis and are arrayed along the axis on a plane parallel to the first principal surface; a plurality of second coil wirings that are provided to a second principal surface side with respect to the axis and are arrayed along the axis on a plane parallel to the second principal surface; a plurality of first through wirings that extend from the first coil wiring side toward the second coil wiring side and are arrayed along the axis; and a plurality of second through wirings that extend from the first coil wiring side toward the second coil wiring side, are provided to the opposite side from the first through wirings with respect to the axis, and are arrayed along the axis. The first coil wirings, the first through wirings, the second coil wirings, and the second through wirings are connected in the stated order and thereby constitute at least part of the helical shape. A reference coil wiring, which is the one of the first coil wirings and the second coil wirings constituting an outermost turn of the first external electrode-side coils that is located electrically closer to the first external electrode, has a shorter length than the length of an adjacent coil wiring that is located on the same plane as that of the reference coil wiring and adjoins the reference coil wiring in the axial direction.
