1. A power transmitting/receiving device that transmits and/or receives electric power in a wireless power transfer system that transfers the electric power wirelessly via a resonant magnetic field, the device comprising:
- an antenna with an inductor; and
a heat dissipation structure with an electrically conductive thermal conductor, a portion of which makes thermal contact with the inductor with an electrical insulator interposed between the conductor and the inductor and which is arranged to form no electrically closed loop.
