A contactless power supply system (1): comprises a power supply coil (20) installed on the ground, an inner balloon (30a) having the power supply coil mounted thereon and capable of expanding and contracting to adjust the vertical position of the power supply coil, and an outer balloon (30b) which is provided so as to cover both the power supply coil and the inner balloon and expands to occupy the space between the power supply coil and a power receiving coil (50); and contactlessly supplies power from the power supply coil to the power receiving coil. Thereby, it is possible to provide a contactless power supply system enabling a long-distance transmission of power without increasing the price of the system and enlarging the system. |
