A connector (1) includes a plurality of connector terminals (3), core resin portions (2A), (2B), nuts (4) and an outer resin portion (5). A plurality of the nuts (4) are arranged to face a nut facing surface (21A) of the core resin portion (2A). The outer resin portion (5) covers the core resin portions (2A), (2B) and the nuts (4) with exposed surfaces (25) of the core resin portions (2A), (2B) and outer end surfaces (41) of the nuts (4) exposed. Injection marks (51) during molding of the outer resin portion (5) are formed on a surface of a part of the outer resin portion (5) covering an opposite side surface (22B) located on a side opposite to the nut facing surface (21A).
