Abstract
There is provided a condenser microphone unit in which the shield of a shielding member that covers a front acoustic terminal from the inside of a unit case is assured to prevent noise caused by electromagnetic waves radiated especially from a cellular phone from being generated. In a condenser microphone unit including a metallic cylindrical unit casehaving a front acoustic terminalon one end side; an electrostatic acousto-electric converterhoused in the unit case; and a shielding memberdisposed between the acousto-electric converterand the front acoustic terminalto cover the front acoustic terminalfrom the inside of the unit case, as the shielding member, there is used a shielding plateconsisting of a metallic porous plate integrally having a plurality of locking pieces, which dig into the inner wall surface of the unit caseon account of elastic deformation, in the peripheral edge part thereof.
