PROBLEM TO BE SOLVED: To obtain a capacitor microphone which enhances the degree of freedom in the design of a circuit board.SOLUTION: A capacitor microphone includes a unit case 1 having a space 12 for holding a capacitor microphone unit 2 and continuous to the rear acoustic terminal 21 thereof, with an opening 13 continuous to the space 12 being formed in the peripheral wall, a volume limit member 3 for reducing the volume of the space 12 by sectioning, a circuit board 4 arranged in the space 12 and surrounded by the volume limit member 3, and a rigid conductor 15 for electrically connecting the signal output end of the microphone unit 2 and the circuit board 4. The circuit board 4 is arranged in a position traversing the center axis of the unit case 1, the rigid conductor 15 is held slidably while being guided by the volume limit member 3, and an elastic conductor 16 is interposed, while being compressed, between the rigid conductor 15 and the circuit board 4, or between the rigid conductor 15 and the signal output end of the microphone unit 2. |
