1. A power transmitting apparatus that wirelessly transmits power to a power receiving apparatus, the power transmitting apparatus comprising:

  • a power transmission unit configured to perform wireless power transmission to a power receiving apparatus arranged within a predetermined power transmission range;

    a detection unit configured to detect a change of an output impedance of the power transmission unit in a case where a predetermined detection signal has been transmitted by the power transmission unit;

    a receiving unit configured to receive a message indicating that a communication scheme for performing communication with respect to the wireless power transmission by the power transmission unit is supported after detecting the change of the output impedance by the detection unit;

    a discrimination unit configured to discriminate whether or not information indicating that a wireless power transmission service is supported is included in the message received by the receiving unit; and

    a control unit configured to, in a case where the discrimination unit discriminates that the information is included in the message, determine that a transmission source of the message is a target for the wireless power transmission by the power transmission unit, and, in a case where the discrimination unit discriminates that the information is not included in the message, determine that a transmission source of the message is not a target for the wireless power transmission by the power transmission unit.
