A microphone structure has a diaphragm; a frame of which an inside is processed in a shape of a semispherical surface, a parabolic surface, or a conical surface; an acoustic transducer that converts sound pressure into an electric signal; and a wire that transmits the electric signal from the acoustic transducer to outside. A sound pressure input surface of the acoustic transducer is disposed on a bottom surface portion of the semispherical surface, the parabolic surface, or the conical surface inside the frame. The diaphragm and the frame, and the frame and the wire include waterproof mechanisms preventing ingress of water.
