A conductive damper for use in a speaker is provided, the endurance and the moldability of which are improved. A base is moved downward to allow an inner top mold to abut on a bottom mold, then the base is further moved downward to allow the inner top mold and the bottom mold to be applied pressure and the base moves down with being guided by guiding means. At this time, energizing means energizes the inner top mold to press the bottom mold, thereby corrugations for the inner part of a workpiece of the conductive damper are molded. At this time, the workpiece of the conductive damper is pulled toward the inner side thereof. Then, the base is further moved downward to press an outer top mold onto the bottom mold, thereby corrugations for the outer part of the workpiece of the conductive damper are molded.
