<P>PROBLEM TO BE SOLVED: To provide a wireless power supplying system that supplies power with high power-supply efficiency without requiring an exclusive measuring instrument or the like. <P>SOLUTION: A power transmission device 20 includes a first resonant element 211 supplied with power so as to transmit the power. A repeater device 40 includes a second resonant element 411 for transmitting the transmitted power while receiving the transmitted power based on a magnetic field resonance relation. A power reception device 30 includes a third resonant element 311 for receiving the power transmitted from the repeater device 40 based on a magnetic field resonance relation. The repeater device 40 includes a drive portion 42 capable of adjusting at least either of the arrangement angle and the arrangement position of the second resonant element 411 according to power transmission information of at least either of the power transmission device 20 and the power reception device 30. <P>COPYRIGHT: (C)2011,JPO&INPIT |
