PROBLEM TO BE SOLVED: To provide an energy supply coil uniforming (or a value close thereto) a magnetic field strength in a coil irrelevant to locations. SOLUTION: This energy supply coil Ba, or an example of the energy supply coil includes a coil group having three or more coils in series and a voltage larger than a voltage impressed on the coil at the center whose magnetic field intensity becomes the strongest, is impressed on the coils at both ends whose magnetic field strength is weakest in the coil group.
