PROBLEM TO BE SOLVED: To provide a power transmission system capable of preventing remarkable reduction in power transmission efficiency caused by unconformity between a primary resonator coil and secondary resonator coil.SOLUTION: A power transmission system comprises: a primary resonator 150 which is provided on the ground and includes a primary resonator coil 160 obtained by winding a conductor wire; and a secondary resonator 250 which is arranged so as to be opposite to the primary resonator 150, includes a secondary resonator coil 260 obtained by winding a conductor wire, and receives electric energy from the primary resonator 150 through an electromagnetic field. The primary resonator coil 160 includes a widening part 340 whose width extends into the inner peripheral side of the primary resonator coil 160. |
