PROBLEM TO BE SOLVED: To provide an input/output connector which achieves excellent heat radiation performance.SOLUTION: A receptacle connector 10 defines a port 30. The port has a spring finger formed so as to engage with a fitting module. The spring finger thermally connects with a heat transmission plate which may be formed so as to provide a part of a cage defining the port. A fin 300 is attached to or integrally provided at the heat transmission plate. During the operation, heat energy from the inserted module is transmitted from the module to the spring finger, then is transmitted to the heat transmission plate, and further is transmitted to a heat radiation system.
