This sensor sheet (18) comprises: an insulating insulator sheet (24); a first electrode sheet (25) that is formed of a first conductive fabric (41) having a first plating layer (44) composed of metal on the surface thereof, and is disposed on one surface o...

A power transmission apparatus oscillates alternating current power at a first frequency (f1) which is lower than a resonant frequency (fr) of the second resonator and at a second frequency (f2) which is higher than the resonant frequency (fr). The power t...
