The connector includes: at least one contact; a housing to which the contact is arranged; a shell formed into a cylindrical shape inside of which the housing is disposed; and a joining member formed of a resin material; wherein the housing and the contact form an integral unit by means of the joining member, and the joining member is closely fitted within an inner surface of the shell or the joining member is integrally coupled to the inner surface of the shell. Thus, the number of components of the connector can be reduced but the manufacturing flexibility thereof can be increased and the connector can be easily miniaturized and manufactured.
