By a simple configuration, contact members can be well retained with a housing in a mutually opposed state, and productivity can be improved. When the contact members in the mutually opposed state are to be attached to the housing, a contact retainer prepared by molding in advance is used by disposing the contact retainer in part of the contact opposed region. As a result, the contact members are stably retained in the mutually opposed state even in injection molding molds. Even in a case in which the contact members normally cannot be retained in the mutually opposed state in the injection molding molds, the housing and the contact members can be integrally molded by well retaining the contact members in the mutually opposed state by using the contact retainer and a contact retainer auxiliary and executing an injection molding process.
