Summary:PROBLEM TO BE SOLVED: To reduce a feeling of inarticulation of a sound that an ear hole type hearing aid user has by making a vent hole much larger than heretofore. SOLUTION: The hearing aid comprises a shell (10) forming the external shape of the hearing aid, a vent hole (20) linking an outer side and a front inner side of the shell (10) to each other, a microphone (13) disposed on the outer side of the shell (10), and a receiver (14) disposed on the front inner side of the shell (10). A bypass wall (25) is formed at an outer opening of the vent hole (20) without closing the vent hole (20). Flexibility of design associated with the size of the vent hole is ensured and a feeling of inarticulation of a sound that the user has is reduced. COPYRIGHT: (C)2008,JPO&INPIT
