Abstract
A power transfer system is provided with a transmission coil and a reception coil respectively provided along a first surface and a second surface that face each other proximal to each other. The transmission coil and reception coil are provided proximally to be electromagnetically coupled to each other. The winding wire of the transmission coil is wound on the first surface, and the winding wire of the reception coil is wound on the second surface. The power transfer system is provided with a magnetic body provided proximately so as to be electromagnetically coupled to the transmission coil and the reception coil to cover at least one part of a region in which at least the winding wires of the transmission coil and reception coil are present between the first surface and the second surface.
