A silicone capacitor microphone is provided to intercept external noise such as electromagnetic noise by forming a plating layer on an inside, an outside or a whole surface of a resin body. A silicone capacitor microphone includes a case(110) and a substrate(120). The case(110) includes a body(112) and a plating layer(114). The body(112) is made of a resin. One surface of the resin is open. The plating layer(114) is formed at the body(112). The substrate(120) includes an MEMS(MicroElectroMechanical System) microphone chip(10), an ASIC(Application-Specific Integrated Circuit) chip(20), and a coupling pattern(121). The ASIC chip(20) processes an electric signal of the MEMS microphone chip(10). The coupling pattern(121) is coupled to the case(110). |
