Title:
METHOD OF MANUFACTURING ELECTRONIC COMPONENT, ELECTRONIC COMPONENT
Document Type and Number:
Japanese Patent JP2015126198
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing an electronic component having large self-inductance L and allowable current with good yield, while facilitating compaction.SOLUTION: A method of manufacturing an electronic component 10 includes a coil formation step of forming at least one coil pattern layer 13 where at least a part of a coil pattern is formed of a conductor on one plane, and at least one insulation resin layer 12 formed of an insulation resin, while laminating sequentially, forming a coil by at least one coil pattern layer 13, and forming a coil fixing body 15 for fixing the coil pattern layer 13 of the insulation resin, a magnetic material adhesion step of forming a magnetic material part 11 so as to cover the coil fixing body 15 entirely with a composite magnetic material mixing magnetic material particles and resin, a pressurizing step of molding while pressurizing the entirety, and a hardening step of hardening the magnetic material part 11.
