WIPO Patent Application WO/2018/079062

A1

Provided is a method for producing a coil component, which is capable of further improving the performance of a coil component. A method for producing a coil component according to the present invention comprises: a step for preparing an element in which a plurality of metal pins are embedded in such a manner that one end parts of the plurality of metal pins are exposed in a first surface of the element, which is a molded body that contains magnetic material particles, and the other end parts of the plurality of metal pins are exposed in a second surface of the element; a step for arranging a plurality of metal plates supported by a support member on the first surface of the element such that one end part of one metal pin and one end part of another metal pin are electrically connected to each other by a metal plate in the first surface of the element; a step for arranging a plurality of conductors on the first surface of the element such that the other end part of one metal pin and the other end part of another metal pin are electrically connected to each other by a conductor in the second surface of the element; and a step for removing at least a part of the support member after electrically connecting the one end parts of the plurality of metal pins and the plurality of metal plates to each other.
