PROBLEM TO BE SOLVED: To provide a hearing aid whose size matches the size of an individual external auditory meatus so as to avoid production of a pain at the insertion of the hearing aid therein and that cannot fall off from the external auditory meatus due to a motion of the chin caused when taking food or in conversation. SOLUTION: An antislip section 14 that is in contact with a comparatively soft part of the ear of a user toward the tragus in the vicinity of the entrance of the external auditory meatus is provided to an outer surface of an auditory meatus insertion section 12 that contains and incorporates a hearing aid circuit 15 and a speaker 16 and the antislip section 14 is manufactured by wax that is adhered to the section 12 and formed through thermal melting in this hearing aid.
