In a condenser microphone where a microphone capsule and an output module section are connected to each other via a microphone code, strong electromagnetic waves generated from a cellular phone or the like are positively prevented from entering the output module section through the microphone code. The condenser microphone in which a microphone capsule 10 and an output module section 20 are connected to each other via a microphone code 30 composed of a twin-core shield covered wire, the microphone capsule 10 including a condenser microphone unit 12 and an impedance converter 13, the output module section 20 storing, in a shield case 21, a circuit board 22 including a voice output circuit, wherein a shield covered wire 33 of the microphone code 30 is connected to the shield case 21, and the shield covered wire 33 is also connected to a ground circuit of the circuit board 22 via a high-frequency choke coil 51.
