1. A electric power transmitting apparatus that has a sub-electric power transmission mode, and a main electric power transmission mode in which a larger amount of power than an amount of power transmitted in the sub-electric power transmission mode is transmitted, and that transmits power to a electric power receiving apparatus in a manner in which a plurality of electric power transmitting apparatuses and electric power receiving apparatuses mainly utilize an identical frequency as a electric power transmission frequency, the electric power transmitting apparatus comprising:

  • a power transmitting section that transmits power wirelessly;

    a communication section that acquires a power request notification to be transmitted from the electric power receiving apparatus; and

    a electric power transmission control section that, as the sub-electric power transmission mode, controls power to be transmitted by the power transmitting section and a transmission timing of the power so that at least power required for the electric power receiving apparatus to transmit the power request notification is transmitted at random time intervals, and that switches to the main electric power transmission mode in a case where the communication section acquires the power request notification.
