The paddle is inserted into a receptacle located in a vehicle for charging a battery in the vehicle. A container, which is made of conductive resin, is located in the paddle to surround lines separated from the cable. Conductive plating layers are formed on the inner surface of the container. Noise radiated from the lines is absorbed by the plating layers and converted into a noise current. The noise current is conducted to a grounding member of the electricity supplying apparatus through a shield located in the cable. The noise current is also conducted to a grounding member of the vehicle through the receptacle. The plating layers permit the noise current to smoothly flow. ## Claims ### Claim 1 A paddle of an inductive charger coupling, the paddle being connected to a power source through a power line, part of the power line being located in the paddle, wherein the paddle is inserted into an opening of a receptacle for supplying electricity to a receptacle, the paddle comprising: a case;
