Abstract: [Technical Problem] In regard to an ear mold for a hearing aid, there are provided the ear mold which a metal bush is settled in a tube for joint of the hearing aid, said metal bush has been used on account of settlement of said tube for joint of the hearing aid, and which a tube is adhered by an adhesive, the adhesive has been used on account of settlement of said tube. However, said ear mold has disadvantages that said tube is easily moved for the reason of instability, said tube drops out from the ear mold, and the ear mold occurred the problem of a phenomenon of a howling by sound leak-out. [Technical Solution] The ear mold which is configured by embedding a connection and fixation member (A hub) 2 having a hole for connection to a hearing aid body and an introductory-hole of a forming material of said ear mold 2010 into the ear mold 1 on the basis of an ear impression. The connection and fixation member (the hub) 2 is embedded into the ear mold 1 when molding of the ear mold.
