Abstract
To provide a wireless power receiving device and an electronic device having the wireless power receiving device whose production costs do not increase even when frequency of electromagnetic waves received for power supply varies. Further, to provide a wireless power receiving device capable of power transmission without disconnection or poor connection when a load supplied with electricity and a battery connected to an antenna are manufactured in different steps. A power transmitter and receiver portion having first and second antenna circuits and a battery portion and a load portion having a third antenna circuit are provided to charge a battery of the battery portion with a first radio signal received at the first antenna circuit and transmit electricity stored in the battery portion as a second radio signal from the second antenna circuit to the third antenna circuit so that the third antenna circuit supplies electricity to the load.
