To search for a communication device other than a power reception device before the power reception device is detected and power feeding is started, to prevent power feeding to the communication device other than the power reception device.SOLUTION: A power feeding device has: communication means that performs a plurality of pieces of polling processing; and power transmission means that wirelessly transmits power to a power reception device. When an object different from the power reception device and responding to any of the plurality of pieces of polling processing is detected by the plurality of pieces of polling processing in a plurality of communication systems in an NFC, the power transmission means limits a power of power transmission to the power reception device, and receives identification information of the power reception device.SELECTED DRAWING: Figure 6
