To obtain a composite type microphone, the microphone preventing an increase in size and weight and thereby improving the freedom for installation and handling while keeping the phases of signals output from respective microphone units the same. A composite type microphone that incorporates microphone units of different electroacoustic conversion methods into a common microphone body is provided. Here, in a front acoustic terminal portion of a first microphone unit based on one electroacoustic conversion method, a second microphone unit based on another electroacoustic conversion method is disposed, and in the front acoustic terminal portion of the first microphone unit, an air that vibrates in the same phase with that of a vibrating plate of the first microphone unit exists, and within the air that vibrates in the same phase with that of the vibrating plate of the first microphone unit, the second microphone unit is disposed.
