<p>Disclosed is an extension cord for a contactless electricity-supplying device that has, at an electricity-receiving section at one of the end-sides thereof, an electricity-receiving coil wound around an electricity-receiving core, which is for magnetically coupling with a magnetic core of a power-supply side electricity-supplying unit. The extension cord for a contactless electricity-supplying device also has, at the other of the end-sides thereof, an electricity-supplying coil wound around an electricity-supplying core, which is for magnetically coupling with a magnetic core of a load-side electricity-receiving unit. Furthermore, an AC-DC converting unit and a DC-AC converting unit are provided between the aforementioned electricity-receiving coil and the aforementioned electricity-supplying coil, and an electricity-transmitting unit connects the aforementioned electricity-receiving coil and the aforementioned AC-DC converting unit, the aforementioned AC-DC converting unit and the aforementioned DC-AC converting unit, or the aforementioned DC-AC converting unit and the aforementioned electricity-supplying coil.</p> |
