In an integral type condenser microphone having a flexible pipe, noise is prevented from being generated even if a cellular phone that radiates strong electromagnetic waves is used at close range. In the gooseneck condenser microphone configured so that a microphone body M in which a microphone unit 10 and an output module part 20 are integrated with each other is supported by a support pipe 30, on a shield housing 20a of the output module part 20 connected to the support pipe 30 via a connecting member 20b, a metal cover 60 for closing the rear end side of the shield housing 20a is put; a shield cover conductor 43 of a microphone cable 40 and the grounding part of a sound signal output circuit 21 are connected electrically to the metal cover 60; the shield housing 20a and the support pipe 30 are insulated electrically from each other; and a completed shield in which the contact portion between the metal cover 60 and the shield housing 20a is the base point of grounding is provided to the output module part 20.
