INTERFACE DEVICE OF COIL CONDUCTIVE WIRE FOR WIRELESS CHARGING OF ELECTRIC VEHICLE, COUPLING STRUCTURE OF COIL CONDUCTIVE WIRE AND INTERFACE DEVICE, AND WIRELESS CHARGING PAD USING COUPLING STRUCTURE

Disclosed is an interface device that has one end forming a coil structure and is coupled to one end of both ends of a coil conductive wire formed by a plurality of conductive wire elements extending in a first direction, which is the direction of a current path, and being arranged in parallel, so as to provide an electrical connection with the coil conductive wire, wherein in a cross-section perpendicular to the first direction of the coil conductive wire, the plurality of conductive wire elements are arranged to be spaced apart from each other by a first predetermined interval.
