A ground-side power feeding device includes a ground-side power feeding coil that wirelessly transmits or receives power to or from a vehicle-side power feeding coil mounted in the vehicle via a magnetic field having a first frequency, a light emitting unit that is disposed at any position at least around the ground-side power feeding coil and in an upper portion of the ground-side power feeding coil when the ground-side power feeding coil is seen from above, and a light emitting power transmitting coil that wirelessly transmits power to the light emitting unit. The light emitting unit has a light emitting power receiving coil which wirelessly receives power from the light emitting power transmitting coil via a magnetic field having a second frequency different from the first frequency, and a light emitting body which emits light with power received by the light emitting power receiving coil.
