A device is realized, with a simpler configuration, that is capable of switching a supply source to a power storage device without interrupting power supply to a recipient of power even if the power supply from a main power source is shut off. Provided is a wiring section to which a voltage is applied based on the output from the main power source in a normal condition; a wiring section provided between a power storage device and the wiring section; and a diode provided between the two wiring sections. The diode restricts the flow of current between the wiring sections when the voltage of the battery wiring section is smaller than the voltage of the main wiring section and allows the flow of current from the battery wiring section to the main wiring section when the voltage of the battery wiring section is greater.
