PROBLEM TO BE SOLVED: To provide a power transmission system which suppresses generation of noise and reduces leakage of noise.SOLUTION: A power transmission system for transmitting electric energy to a secondary resonator 250 including a secondary resonator coil 260 through an electromagnetic field having a predetermined frequency generated by a primary resonator 150 including a primary resonator coil 160 comprises a noise cancel resonator 300 which includes a noise cancel resonator coil 310 and has a resonant frequency higher than the predetermined frequency by a shift frequency determined depending on the degree of coupling between the primary resonator coil 160 and the noise cancel resonator coil 310. The noise cancel resonator coil 310 is arranged so that a direction of a magnetic field generated by the primary resonator coil 160 and a direction of a magnetic field generated by the noise cancel resonator coil 310 are in parallel with each other. |
