Title:
INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2020/183993
Kind Code:
A1
Abstract:
An inductor 1 is provided with a wire 35 and a sheet-shaped magnetic layer 4 in which the wire 35 is embedded. The wire 35 is provided with a conductor 2 and an insulating film 3 positioned on the circumferential surface of the conductor 2. The magnetic layer 4 contains at least 40 vol% of anisotropic magnetic particles 8. When viewed in at least two planar cross-sections among a first planar cross-section 11, a second planar cross-section 12 and a third planar cross-section 13 along the surface direction of the magnetic layer 4, in a first direction that is orthogonal to a flow direction and a thickness direction, an alignment area in which the anisotropic magnetic particles 8 are aligned in the flow direction is observed in a proximity area 10 within 50 μm to the outside from the outer edge 30 of the insulating film 3, in the first direction. The first planar cross-section 11 passes through a midpoint MP of a line segment L of the conductor 2. The second planar cross-section 12 passes through a first point P1 which is a position where a length 1/4 L extends to one side in the thickness direction from the midpoint MP. The third planar cross-section 13 passes through a second point P2 which is a position where the length 1/4 L extends to the other side in the thickness direction from the midpoint MP.
