<P>PROBLEM TO BE SOLVED: To restrain unwanted radiation of electromagnetic waves in radio power transmission, and to restrain a decrease in efficiency of power transportation as much as possible. <P>SOLUTION: In a method of shielding electromagnetic waves in a radio power transmission system 1 utilizing a magnetic field to transmit power by radio from a power transmission system coil SC to a power reception system coil JC, a power-transmission-side magnetic shielding member 31 comprising a magnetic body is disposed at a side opposite to a power transmission side by the power transmission system coil SC in the power transmission system coil SC, and an electric field shielding member 33 comprising a conductive material is disposed at a side orthogonally crossing a power transmission direction by the power transmission system coil SC. Also, a power-reception-side magnetic shielding member 32 comprising a magnetic body is disposed at a side opposite to a power reception side by the power reception system coil JC in the power reception system coil JC. <P>COPYRIGHT: (C)2011,JPO&INPIT |
