The invention provides a close-talking type microphone which can shut a sound under a loud sound environment and does not make it hard or impossible for receivers to recognize a target sound due to a significant reduction of a quality of receiving the target sound. The microphone is provided with an outer casing having an open front surface, an inner casing having a front wall provided with a sound hole in a center portion, the front wall closing the front surface, having a space on a peripheral surface and a rear surface, and inserted to the outer casing, a sound pressure-electricity conversion unit fitted and held in the inner casing so as to direct a vibrating body toward the sound hole and a porous cap member covering the front surface of the front wall. The inner casing is made of a vibration isolating material, and the space is filled with a sound absorbing material constituted of a fiber laminated material.
