A contactless power feeding system includes: a primary circuit for supplying primary power to a power feeding coil; and a primary control circuit for controlling the primary circuit. The primary control circuit acquires, from a secondary control circuit, a secondary measured value and a secondary target value of secondary power received by a power receiving coil. The primary control circuit performs control processing and update processing alternately and repeatedly. The control processing is processing of controlling the primary circuit to bring the primary measured value into conformity with a primary target value. The update processing is processing of updating the primary target value. The update processing includes processing of calculating the primary target value based on transfer efficiency to be determined by the primary measured value and the secondary measured value and on the secondary target value.
