A non-contact power transmission system comprises: a primary coil including a power supply coil and a magnetic resonance coil; and a secondary coil including a load coil, thereby transmitting an electric power from the power supply coil at a self-resonating frequency of the magnetic resonance coil, which is determined by a parasitic capacitance between wound wires of the coil and a self inductance of the coil, and taking out the electric power supplied, from the load coil of the secondary coil through magnetic coupling, with non-contact, wherein the electric power is transmitted, with non-contact, with applying magnetic coupling in coupling between the power supply coil and the magnetic resonance coil and coupling between the magnetic resonance coil and the load coil. |
