ANTENNA FOR ELECTRIC POWER TRANSMISSION, ELECTRIC POWER TRANSMISSION DEVICE, AND CONTACTLESS TYPE ELECTRIC POWER TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an antenna for electric power transmission capable of securely transmitting electric power to an electric power reception device side wherever an antenna on the side of the electric power reception device is when used for an electric power transmission device.SOLUTION: Side parts A1, A5 forming parts of a transmission antenna 12 constituted by winding a conductor 6 by one turn or two or more turns are positioned in a plane PL2 crossing a plane PL1 containing other side parts A2, A3, and A4 constituting the remaining parts of the transmission antenna 12 to constitute a structure which is plane-asymmetrical on the whole.
