Document Type and Number:
WIPO Patent Application WO/2019/220862
Kind Code:
A1
Abstract:
An inductor (101) is equipped with: a substrate (1) having a main surface (1u); a plurality of arranged first conductors (21); a first insulating layer (31) which is positioned on the main surface (1u) and separates the plurality of first conductors (21) from one another; a second insulating layer (32) which is positioned above the top surfaces of the plurality of first conductors (21); a magnetic core (5) which is positioned above the second insulating layer (32); a third insulating layer (33) which covers the top and sides of the magnetic core (5); and a plurality of second conductors (22) which are positioned so as to straddle the top of the third insulating layer (33) and are connected to the plurality of first conductors (21). Therein, the top surfaces of the plurality of first conductors (21) and the top surface of the first insulating layer (31) are positioned within the same plane, and a coil structure is formed by alternatingly connecting the first conductors (21) and the second conductors (22) with one another.
