1. A power receiving apparatus forming a pair with a power transmitting apparatus in which a high-frequency voltage generator circuit that applies a high-frequency high voltage is connected between a power transmitting apparatus side active electrode and a power transmitting apparatus side passive electrode, the power receiving apparatus comprising:

  • a power receiving apparatus side active electrode that faces the power transmitting apparatus side active electrode with the power receiving apparatus mounted to the power transmitting apparatus;

    a power receiving apparatus side passive electrode that faces the power transmitting apparatus side passive electrode with the power receiving apparatus mounted to the power transmitting apparatus;

    a voltage step-down circuit that decreases a voltage generated between the power receiving apparatus side active electrode and the power receiving apparatus side passive electrode; and

    a load circuit that receives an output voltage of the voltage step-down circuit as a power supply voltage,wherein the power receiving apparatus side active electrode and the power receiving apparatus side passive electrode are not parallel with each other in terms of a positional relationship.
