Provided is a electric power transmitting apparatus (300) that has sub-electric power transmission mode, and main electric power transmission mode for transmitting power larger than that transmitted in the sub-electric power transmission mode. A power transmitting unit (310) transmits power in a wireless manner. A electric power transmission control unit (320) controls, in sub-electric power transmission mode, power to be transmitted by means of the power transmitting unit (310) and transmission timing of the electric power transmission such that at least power that the electric power receiving apparatus needs to transmit power request notification is transmitted at random intervals. A electric power transmission control unit (320) performs switching to the main electric power transmission mode, in the cases where a communication unit (350) acquired the power request notification transmitted from the electric power receiving apparatus. |
