PROBLEM TO BE SOLVED: To provide a power receiving coil which matches the impedances.SOLUTION: The power receiving coil includes an antenna coil, a primary coil, a secondary coil, and a soft magnetic body. Both ends of the antenna coil and both ends of the primary coil are interconnected. The primary coil surface is covered at least partially with the soft magnetic body, and the secondary coil surface is covered at least partially with the soft magnetic body. The primary coil and secondary coil are coupled magnetically via the soft magnetic body, and the power received by the antenna coil is subjected to impedance conversion by means of the primary coil and secondary coil before being received by the power receiving coil. |
