Claims

[Scope of utility model registration request]

A conductor is passed through a through hole in the center of the substrate, and spiral first and second coils made of thin foil material are formed on the upper and lower surfaces of the substrate, respectively, with their center ends connected to the conductor. A secondary coil is formed by making the direction of the spiral from the center end of the first coil as viewed from above the same as the direction of the spiral from the center end of the second coil as seen from below,
A charging device in which a secondary coil is arranged on an end face of a cylindrical primary coil for electromagnetic coupling, and both ends of the secondary coil are connected to a storage battery via a rectifying semiconductor element.
