Abstract
The present invention provides a power transfer system capable of reducing electromagnetic energy that disappears into a medium as a resistor when the coil of a power transmitting device and the coil of a power receiving device are apart from each other, in such a way that the power transmitting device of the power transfer system is equipped with a backside dielectric body and a shield body. A power transmitting device () faces a power receiving device () through a medium. The power transmitting device () comprises: a power transmission coil (); a containment portion () having a first surface (A) facing the power receiving device and a second surface (B) on the opposite side of the first surface and having a dielectric body covering the power transmission coil (); a backside dielectric body () provided on the second surface (B) of the containment portion and having a first surface (A) facing the containment portion and a second surface (B) on the opposite side of the first surface; and a shield body () provided on the second surface (B) of the backside dielectric body.
