Method of manufacturing an electronic component
First Claim
1. A method of manufacturing an electronic component, the method comprising:
- a coil forming step of forming a coil by a wire-shaped conductor;
a press fitting step of embedding the coil into a plate-shaped composite magnetic material in a state in which the plate-shaped composite magnetic material is softened, the plate-shaped composite magnetic material being a first composite magnetic material that is formed in a plate shape and in which magnetic particles and a resin are mixed, each of upper and bottom ends of the coil being partially exposed;
a covering step of disposing second and third plate-shaped composite magnetic materials which are soften on top and bottom of the soften first composite magnetic material, respectively, so as to cover a part of the coil with the second and third plate-shaped composite magnetic materials, the part of the coil being a part remaining uncovered on each of the upper and bottom ends of the coil in the press fitting step;
a pressurizing step of pressurizing and molding an entirety; and
a hardening step of hardening the composite magnetic material.

Abstract
A method of manufacturing an electronic component includes: a coil forming step of forming a winding coil by a wire-shaped conductor; a press fitting step of embedding the winding coil into a plate-shaped composite magnetic material in a state in which the plate-shaped composite magnetic material is softened, the plate-shaped composite magnetic material being a composite magnetic material that is formed in a plate shape and in which magnetic particles and a resin are mixed; a covering step of covering a part of the winding coil with another plate-shaped composite magnetic material that is softened, the part of the coil being a part remaining uncovered in the press fitting step; a pressurizing step of pressurizing and molding an entirety; and, a hardening step of hardening the composite magnetic material.
