Document Type and Number:
WIPO Patent Application WO/2020/183997
Kind Code:
A1
Abstract:
An inductor 1 comprises: wire 2 which has a conductor 4 and an insulating film 5 positioned on the entire peripheral surface of the conductor 4; and a magnetic layer 3 in which the wire 2 is embedded. The magnetic layer 3 comprises magnetic particles 60. The magnetic layer includes: a first layer 10 in contact with a first surface 7 of an outer peripheral surface 6 of the wire 2; and a second layer 20 in contact with the surface of the first layer 10 and with a second surface 8 of the outer peripheral surface 6 of the wire 2.
