Document Type and Number:
WIPO Patent Application WO/2019/142861
Kind Code:
A1
Abstract:
In this invention, heat dissipation in an inductor comprising a rectangular wire having a flatwise wound structure is improved to provide an inductor applicable for use in a high-frequency band environment, an inductor-equipped device, and an inductor production method. This inductor (1) comprises a plurality of coil parts (10, 20), each having a rectangular wire (2) wound flatwise and layered with a gap provided therebetween in the radial direction, and the plurality of coil sections (10, 20) being aligned with a gap provided therebetween in the axial direction. By providing gaps between the plurality of coil parts, air flows through the gaps, allowing heat dissipation to be improved.
