1. A resonance-type non-contact power supply system which comprises a power-transmission-side resonance coil part and a power-receiving-side resonance coil part, and which transmits electric power by a non-contact resonance effect from the power-transmission-side resonance coil part to the power-receiving-side resonance coil part, the system further comprising:

  • a first coaxial cable which electrically connects a high frequency power supply and the power-transmission-side resonance coil, anda power-transmission-side shield part which is a good conductor and covers from outside to accommodate the power-transmission-side resonance coil part, and which is electrically connected to a housing of the high frequency power supply by an outer conductor of the first coaxial cable, whereina size of the power-transmission-side shield part is set so that the electromagnetic coupling of the power-transmission-side resonance coil part is not affected,the power-transmission-side shield part accommodates the power-transmission-side resonance coil part not to protrude from the power-transmission-side shield part, anda first transmission opening is provided on a bottom of the power-transmission-side shield part and the outer conductor of the first coaxial cable is connected to an inner edge of the first transmission opening.
