Title:
INDUCTOR AND ELECTRONIC PART COMPRISING INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2023/157666
Kind Code:
A1
Abstract:
The present disclosure provides: an inductor that makes it possible to achieve high coupling coefficients even when parasitic inductance occurs; and an electronic part comprising the inductor. This inductor (100) comprises: an insulator (3); a first coil (L1) and a second coil (L2); and an external electrode (4a) and an external electrode (4c). The external electrode (4a) is disposed on a first main surface (bottom surface) side and is electrically connected to the first coil (L1). The external electrode (4c) is disposed on the first main surface (bottom surface) side and is electrically connected to the second coil (L2). The first coil (L1) and the second coil (L2) are stacked in a direction in which a plurality of insulating layers are stacked, and are magnetically coupled to each other. The second coil (L2) has a smaller inductance value than the first coil (L1) and is disposed on the first main surface side within the insulator (3) with respect to the first coil (L1).
