In the present invention, a charging coil interlinks with a magnetic field from an external charger coil, thereby generating induced electromotive force. A battery is charged by this induced electromotive force. A display device has a display region, and in a planar view the center of the charging coil is included within the contour of the display region. In a first mode wherein the supply of direct-current voltage from the battery to the display device is shut off, when the battery is charged using the induced electromotive force, a control unit supplies direct-current voltage to the display device, displays in the display region a charging screen, which has first information (indicating the center of the charging coil) at a relevant position, and terminates the display of the charging screen after a prescribed amount of time has elapsed. |
