Abstract

The invention provides an inductor component capable of suppressing reliability reduction caused by heat. The inductor component includes a main body 20, a first inductor wiring 30 located inside the main body 20 and extending on a virtual plane S1, and a second inductor wiring 40 located inside the main body 20 and extending in parallel to the virtual plane S1. The inductor component includes a third inductor wiring 50 located between the first inductor wiring 30 and the second inductor wiring 40 inside the main body 20 and extending in parallel to the virtual plane S1. The inductor component includes vertical wirings 61-63 passing through the inside of the main body 20 from each of the first to third inductor wirings 30, 40, 50 to a surface of the main body 20 in a direction perpendicular to the virtual plane S1. The third inductor wiring 50 is a low-resistance inductor wiring 55 having a DC electrical resistance smaller than those of the first inductor wiring 30 and the second inductor wiring 40.

Description

technical field

[0001] The present disclosure relates to inductor components. Background technique

[0002] In an inductor component mounted on an electronic device, for example, as described in Patent Document 1, there is a structure that constitutes an inductor array including a main body and a magnetic material layer that is a sintered body of ferrite laminated. formed; and a plurality of inductor wirings located on the same virtual plane inside the main body.

[0003] Patent Document 1: Japanese Patent Laid-Open No. 2002-110432

[0004] In the inductor component constituting the above-mentioned inductor array, generally, a plurality of inductor wirings are formed so that the wiring width and line length are the same, and the DC resistances are the same. Furthermore, when the inductor component includes three or more inductor wirings aligned on the same virtual plane, the inductor wirings located at both ends of the parallel arrangement direction of the inductor wirings...
