PROBLEM TO BE SOLVED: To provide a method of manufacturing a diaphragm for electro-acoustic transducer with which overflow or short-circuit is prevented when filling clearance of a mold with photo-setting resins, air bubbles are also prevented from being held in and a diaphragm for electro-acoustic transducer can be easily and inexpensively manufactured with a little man-hour, and a diaphragm for electro-acoustic transducer manufactured therewith. SOLUTION: Upper and lower dies are clamped and the clearance of a mold thereof is filled with photo-setting resins from the outside through a gate. Thus, overflow or short-circuit of the photo-setting resins, holding of air bubbles in filling the clearance with resins, etc., are prevented. At least one of the upper and lower dies is comprised of a light transmissible material, and the photo-setting resins are cured by irradiating them with ultraviolet rays or visible light beams from the outside, thereby manufacturing the diaphragm.
