Abstract
There is provided a power receiving device capable of receiving a carrier wave transmitted from a power transmitting device without contact and obtaining electric power from the received carrier wave, which includes a carrier receiving section at least including a communication antenna having predetermined inductance and not equipped with an intermediate tap, to receive the carrier wave and generate an induced voltage corresponding to the carrier wave, a processing section to generate a drive voltage based on the induced voltage and perform data processing using the generated drive voltage, and an impedance converting section to convert impedance between the carrier receiving section and the processing section.
