摘要： A condenser microphone includes: a casing including a sound hole; a vibration film disposed in the casing so as to face the sound hole; a back plate disposed opposed to the vibration film; a spacer disposed between the vibration film and the back plate; and a hold member including a spring member. The back plate has an outer peripheral shape that is smaller than an inner peripheral shape of the casing so as to provide a clearance between an outer peripheral surface of the back plate and an inner peripheral surface of the casing. The back plate is held by the hold member from an opposite side of the vibration fills.
