| 摘要 | A non-contact power reception device includes a load such as a power storage device (150) identified as a subject of power feeding, and a secondary self-resonant coil (110) receiving electric power to be supplied to said load from an external primary self-resonant coil (240). The secondary self-resonant coil (110) is configured so as to be switchable between a first state and a second state. The first state is selected in a power reception mode in which the secondary self-resonant coil is magnetically coupled with the primary self-resonant coil (240) through resonance of a magnetic field. The second state is selected in a power non-reception mode in which the magnetic coupling of the secondary self-resonant coil with the primary self-resonant coil through resonance is weaker than in the first state. | ||||||
