Title:
INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2020/183994
Kind Code:
A1
Abstract:
This inductor (1) has a wire (2) and a magnetic layer (3) that coats the wire (2). The wire (2) has a conductor (6) and an insulating layer (7). The magnetic layer (3) contains anisotropic magnetic particles (8) and a binder (9). In a peripheral region (11) of the wire (2), the magnetic layer (3) has an aligned region (13) in which the anisotropic magnetic particles (8) are aligned along the circumference of the wire (2). In cross sectional view, the peripheral region (11) extends outwards from the outer surface of the wire (2) by a value 1.5 times the average of the maximum length and the minimum length from the center of gravity of the wire (2) to the outer surface of the wire (2). The upper surface and lower surface of the inductor (1) are flat.
