Claims (33)

1 . A hearing aid comprising:

a main body including a battery;

a surface of one side of the main body being in contact with a lower side of a back of an ear corresponding to a cavum concha when the hearing aid is worn; and

a holding portion that supports the main body from the lower side when the hearing aid is worn, the holding portion being detachable from the main body;

wherein,

the main body is provided with a stepped portion on an outer peripheral edge of an other side surface different from the one side surface in contact with the ear, and

the holder includes a fitting portion fitted in the stepped portion and an attaching portion that is formed continuously and integrally with the fitting portion, the attachment portion being attached to the ear when the hearing aid is worn.

2 . The hearing aid according to claim 1 , wherein,
