CONDENSER MICROPHONE

A condenser microphone including vibrating film electrode and fixed electrode is provided to have a flexibility of a mounting method by improving a convenience of separation and mounting. A condenser microphone comprises a case(1), a vibrating film electrode(14), a fixed electrode(23), a condenser part(C), a converting circuit part, and a conductive part(30). The case has a cavity on a ceiling surface. The vibrating film electrode and the fixed electrode are positioned inside the case. In the condenser part, an electric film is formed in the corresponding vibrating film electrode or the corresponding fixed electrode. The converting circuit part converts and outputs a change of an electrostatic capacity of the condenser part into an electric signal. The conductive part electrically conducts the condenser part and the converting circuit part. The case is formed by assembling a first plate-shape member, a second plate-shape member, and an in-between member. The first plate-shape member is comprised the ceiling surface. The second plate-shape member is comprised a floor surface. The in-between member is positioned between the first plate-shape member and the second plate-shape member.
