PROBLEM TO BE SOLVED: To provide a hearing aid which can be inexpensively manufactured, can be efficiently used safely and effectively, and can adapt wisely to the state of an aurally handicapped person. SOLUTION: A hearing aid device includes a voice amplifying means for receiving a voice signal and amplifying the received voice signal, a voice originating means for originating the voice signal amplified by the voice amplifying means, and an induction magnetic field generating means for generating an induction magnetic field by a voice current flowing from the voice amplifying means. They are integrally assembled in a casing to be able to be carried. Thus, since the hearing aid device can be carried, the hearing aid device can be installed at a necessary place comfortably. Since the hearing aid device is easy to move, the hearing aid place can be simply set or changed. COPYRIGHT: (C)2006,JPO&NCIPI
