Disclosed is a power feed system which can highly efficiently feed power to a power receiving unit from a power feed-side even though distance fluctuation or lateral shift occurs between a power feed-side helical coil and a power receiving-side helical coil. A distance measuring unit (13) measures a inter-coil distance L 1 between the power feed-side helical coil (7) and the power receiving-side helical coil (9), and a control units (14), (17) adjust capacitances of a power feed-side varactor (8) and a power receiving-side varactor (11) in accordance with the inter-coil distance L 1 measured by the measuring unit (13). |
