METHOD FOR PRODUCING ELECTRONIC COMPONENT, AND ELECTRONIC COMPONENT

WIPO Patent Application WO/2015/098355

A1

Provided are: a method for producing, with a high yield, an electronic component which has a high self-inductance (L) and a high allowable current, and which is easily miniaturized; and the electronic component. This method for producing the electronic component (10) is provided with: a coil formation step in which a wire-like conductor is used to form wound-wire coils (12); a press-in step in which the wound-wire coils (12) are embedded in a plate-shaped composite magnetic material (111) while the plate-shaped composite magnetic material (111) is in a state of having been softened, said plate-shaped composite magnetic material (111) being obtained by forming, into a plate shape, a composite magnetic material obtained by mixing magnetic particles and a resin; a covering step in which the wound-wire coils (12), having not been completely covered in the press-in step, are further covered with another softened piece of the plate-shaped composite magnetic material (111); a pressurization step in which the whole of the resultant object is pressurized and moulded; and a curing step in which the composite magnetic material is cured.
