PROBLEM TO BE SOLVED: To further minimize an attaching space which is necessary for a coil of a hearing aid. SOLUTION: In the hearing aid having housings HG and IG, and a high-frequency antenna and electric coils, HA, SI and SU for transmitting an electromagnetic energy or data, the high-frequency antenna and the electric coils, HA, SI and SU are formed as a conductive film in materials of the housings HG and IG or in the housings HG and IG, the housings are used as a supporting material for the antenna, and a place to be provided for the antenna, for example, on a printed wiring board thereby can be omitted.
