Japanese Patent JP7294833
Kind Code:
B2
Abstract:
An inductor 1 includes a wire 2, and a magnetic layer 3 covering the wire 2. The wire 2 includes a conducting line 6, and an insulating layer 7 covering the conducting line 6. The magnetic layer 3 includes a magnetic particle and a binder 9. In a peripheral region 4 of the wire 2, a filling rate of the magnetic particle is 40% by volume or more. The peripheral region 4 is a region of the magnetic layer 3 traveling outwardly from an outer peripheral surface of the wire 2 by 1.5 times an average of the longest length and the shortest length from the center of gravity C of the wire 2 to an outer surface of the wire 2 in a cross-sectional view.
