ABSTRACT:
A problem is to provide a sheet-like or thin plate-like coil device that can guarantee a high power transmission efficiency, that has quite little magnetic spurious radiation, that does not cause overheat even in the case of long charge, and that can be manufactured at low cost.The present coil device is characterized in that two spiral patterns composing a basic pattern are each formed into regular triangle, and are arranged in back to back manner sharing each of base side lines of those two triangles so that the basic pattern is formed into a rhombic S-shape as a whole.
