Title:
METHOD FOR MANUFACTURING INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2020/183996
Kind Code:
A1
Abstract:
This method for manufacturing an inductor 1 comprises: a first step in which a wire 2 is positioned on one surface of a substrate in the thickness direction, the wire 2 having a cross section with a substantially circular shape and comprising a conductor 6 and an insulating layer 7 that covers the conductor 6; a second step in which a first magnetic sheet 51, containing first magnetic particles and a first binder 91 in which the first magnetic particles are dispersed, is positioned on one surface of a first release sheet 41 in the thickness direction so as to cover a major arc of the circumferential surface of the wire 2; and a fourth step in which a second magnetic sheet 52, containing second magnetic particles and a second binder 92 in which the second magnetic particles are dispersed, is used to cover one surface, in the thickness direction, of the first magnetic sheet 51 that covers the major arc of the circumferential surface of the wire 2 and the one surface of the first release sheet 41.
