A wireless mouse device is provided to realize semi-permanent usage without replacing a dry cell or recharging a battery by generating induced electromotive force with a permanent magnet embedded in a mouse pad and an induction coil included in a wireless mouse, and supplying power needed for operating a circuit of the wireless mouse and a wireless keyword. A mouse pad(10) includes a first permanent magnet(11). A wireless mouse(20) includes a power supply unit supplying power needed for operating a circuit of the wireless mouse and a first induction coil(25) connected to the power supply unit. Induced electromotive force is induced in the first induction coil by electromagnetic induction between the first permanent magnet and the first induction coil, and is supplied to the power supply unit when a user performs pointing operation on the mouse pad by using the wireless mouse. A second permanent magnet(27) is embedded in the mouse pad and a second induction coil(13) is embedded in the wireless mouse. The induced electromotive power induced between the second permanent magnet and induction coil is provided to the power supply unit of a wireless keyboard(30).
