The invention provides a non-contact power supply system which supplies power from a power feeding coil (12) on a ground side to a power receiving coil (22) on a vehicle side, and provides a coil position detecting method of detecting a position of a power receiving coil. An excitation voltage and an excitation frequency for the power feeding coil (12) are changed depending on the position of the power receiving coil (22) relative to the power feeding coil (12). Then, the position of the power receiving coil (22) is detected based on a received voltage with the power receiving coil (22) when the power feeding coil (12) is excited.
