<P>PROBLEM TO BE SOLVED: To provide a power receiving unit having a power receiving coil and a battery, which can charge the battery efficiently without being affected by a posture of the power receiving unit with respect to a power feeding coil. <P>SOLUTION: A power receiving unit (10) includes a tube-shaped power receiving coil (12) configured such that a current flows therein by magnetic flux generated by energization of a power feeding coil (21), a battery (4) configured to be charged by the current flowing in the power receiving coil (12), and a housing (17) configured to be able to store the power receiving coil (12) and the battery (4). The power receiving coil (12) is disposed in the housing (17) such that both end parts thereof extending in one direction are positioned where the current flows therein by magnetic flux generated in the power feeding coil (21). <P>COPYRIGHT: (C)2012,JPO&INPIT |
