Abstract
A method of manufacturing a speaker diaphragm having a conductive layer and resin layers arranged to interpose the conductive layer is provided. The method includes: a first step of providing a through hole for causing a tinsel wire to pass through a conductive layer; and a second step of closing a mold, in which a punch having a diameter smaller than a diameter of the through hole is provided in each of first and second molds, to cause the punches to press the resin layers on an inside of the through hole with respect to a laminated body in which the resin layers are arranged on both surfaces of the conductive layer. In the second step, leaked material of the resin layers flows in an inner side surface direction of the through hole by pressing into a gap portion near outer surfaces of the punches.
