PROBLEM TO BE SOLVED: To provide a non-contact power supply system, a transmission equipment, a power supply method, and power transmission method capable of suitably stopping power supply without installing communication means to a power reception device.SOLUTION: A transmission equipment 1 determines whether or not a power reception device 3 exists in a power receptable area, and when determining that the power reception device 3 exists in the power receptable area, the transmission equipment 1 transmits a high-frequency AC power. Therefore, when determining that the power reception device 3 does not exist in the power receptable area, the transmission equipment 1 does not transmit a high-frequency AC power. The transmission equipment 1 determines that a charge of a battery 4 is completed in the case where a level of a reflection power of a high-frequency AC power is equal to a threshold value or more even when determining that the power reception device 3 exists in the power receptable area, and stops the power transmission of high-frequency AC power.SELECTED DRAWING: Figure 1 |
