The speaker member includes: a base material; and a resin film layer laminated on the base material through an adhesive layer. The adhesive layer has a heat shrinkage ratio of 0.5 to 1.0%; the resin film layer has a heat shrinkage ratio of 0.8 to 1.3%; and the heat shrinkage ratio of the adhesive layer is smaller than the heat shrinkage ratio of the resin film layer. The method of manufacturing a speaker comprises the steps of: applying a predetermined resin composition on a release material; drying the resin composition, so as to form a resin film layer on the release material; applying a predetermined adhesive on the resin film layer, so as to form an adhesive layer; attaching together the resin film layer formed on the release material and a base material through the adhesive layer, so as to form a laminate; subjecting the laminate to aging; and molding the laminate subjected to aging by using a metal mold having a predetermined shape.
