Abstract
An electrical powered vehicle includes a secondary self-resonant coil, a secondary coil, a rectifier, and a power storage device. The secondary self-resonant coil is configured to be magnetically coupled with a primary self-resonant coil of a power feeding device by magnetic field resonance, and allow reception of high frequency power from the primary self-resonant coil. The secondary coil is configured to allow reception of electric power from the secondary self-resonant coil by electromagnetic induction. The rectifier rectifies the electric power received by the secondary coil. The power storage device stores the electric power rectified by the rectifier.
