Document Type and Number:
WIPO Patent Application WO/2016/163437
Kind Code:
A1
Abstract:
The present invention is provided with a coil that includes: a plurality of first linear conductors (11a-11t) that are formed on a first main surface (S1) side of a laminate body (10); a plurality of second linear conductors (12a-12t) that are formed on a second main surface (S2) side; and first end-surface conductors (21a-21t) and second end-surface conductors (22a-22s) that are formed on end surfaces. The first linear conductors (11a-11t) are constituted by a first main part, a first end part, and a second end part. The second linear conductors (12a-12t) are constituted by a second main part, a third end part, and a fourth end part. The width of the first end-surface conductors (21a-21t) is narrower than the width of the first main parts and the width of the second main parts, and the width of the second end-surface conductors (22a-22s) is narrower than the width of the first main parts and the width of the second main parts.
