Electric power supplying equipment (1) and an electric power receiving device (2) include a primary self resonant coil (30) and a secondary self resonant coil (60), respectively, resonating through an electromagnetic field to allow the electric power supplying equipment (1) to supply the electric power receiving device (2) with electric power in a non-contact manner. A control device (40) controls a high frequency electric power supply device (10) to control supplying electric power from the primary self resonant coil (30) to the secondary self resonant coil (60). The control device (40) estimates a distance between the primary self resonant coil (30) and the secondary self resonant coil (60) from an S-parameter S11 varying with the distance between the primary self resonant coil (30) and the secondary self resonant coil (60), and controls supplying electric power, based on that estimated distance.
