Abstract
Provided is a condenser microphone having a plurality of condenser microphone units connected in series to improve output sensitivity, and a simplified circuit configuration. At least one of the preceding condenser microphone units, excepting a last condenser microphone unit, and an adjacent succeeding condenser microphone unit are directly connected to transmit an audio signal obtained from the at least one of the preceding condenser microphone units to the adjacent succeeding condenser microphone unit. An impedance converter using an active element is connected to the last condenser microphone unit, and the audio signals obtained from the condenser microphone units are added and output from the impedance converter using the active element.
