Disclosed is a remote controller, which eliminates liquid leakage from a dry cell due to a leak current, can be stably used, and has a long service life. The remote controller (4) supplies power to a microcomputer (440) by using both a solar cell (402) and a lithium primary cell (431). On the connecting point between the solar cell (402) and the lithium primary cell (431), a diode OR circuit (455) is used, and power is supplied to the microcomputer (440) from the cell having a higher voltage, said cell being either the solar cell (402) or the lithium primary cell (431). |
