A hearing aid comprises a shell(1) and an ear tip(2) of elastic material. The shell has a cone shape in order to easily install the hearing aid. A diameter of a front(1a) of the shell is small. A diameter of a rear(1b) of the shell is large. The shell includes a curved part(1c). The ear tip has an inner side of the same shape as the shell in order to be installed in an outer side of the shell. Wings(21) are formed into a columnar direction of the outer side of the ear tip. A fixed wing is formed in a rear of the ear tip in order to fix the shell. |
