PROBLEM TO BE SOLVED: To prevent an edge part of a diaphragm material from being easily released from a support ring in a diaphragm for capacitor microphone which is configured by sticking the diaphragm material comprised of a thin film using an adhesive material while giving a predetermined tension to the support ring. SOLUTION: In a diaphragm for capacitor microphone configured by sticking a diaphragm material 10 comprised of a thin film through an adhesive material 30 to one side surface of a support ring 20, an edge part 10e of the diaphragm material 10 is disposed inside rather than an outer diameter end 20b of the support ring 20 all over the full circumference.
