In an optical/electrical composite connector including a male connector and a female connector, the male connector includes a ferrule provided at an end portion of an optical fiber on a side of the male connector which is connected to the female connector, and an electrode terminal. The female connector includes a core to transmit an optical signal, a cladding to cover the core, an electric wiring provided on an outer wall surface of the cladding, a sleeve in which the ferrule is fitted, the sleeve provided at an end portion of the cladding on a side of the female connector which is connected to the male connector, and a lens provided in the sleeve. When the ferrule and the sleeve are fitted together, the electrode terminal and the electric wiring are electrically connected and the optical fiber and the core are optically connected through the lens.
