To provide a compact power feeding device that can efficiently perform non-contact power feeding to a movable member.SOLUTION: A power feeding device 10 feeds power to a seat S that is movable relative to a floor F of a vehicle. The power feeding device 10 includes a power reception unit 20 that includes a power reception coil 24 and moves together with the seat S, a power transmission coil 34 that is arranged by opposing the power reception coil 24 and supplies power without contact to the power reception coil 24, a power transmission extension unit 35 extending from the power transmission coil 34, a power transmission unit 30 that moves together with the sheet S and the power reception unit 20, and an excess length absorbing portion 40 that includes a take-up part 45 that performs winding and feeding of the power transmission extension unit 35 by rotating in conjunction with the movement of the sheet S.SELECTED DRAWING: Figure 2
