A mouse having a retractable cable is provided to utilize space for using the mouse efficiently by freely regulating the length of a connection line of the mouse. A connection terminal(230) is connected with external devices. A connection line(240) transmits added electric power through the connection terminal. A winding roll(270) winds the connection line by rotation. A case member(210) stores the winding roll in an internal space. A control member(260) is coupled with the case member, and controls the length of the connection line which is winded to the winding roll. The connection terminal is composed of a PS/2-terminal or a USB-terminal.
