Abstract:
The present power transmission device performs a power transmission process for transmitting power in a wireless manner through electromagnetic field resonance coupling using a resonance circuit. In a case where a resonance frequency of the resonance circuit set to be the same as a frequency of a power transmission signal which is output as transmission power is deviated during transmission of the power, the present power transmission device detects a direction in which the resonance frequency is deviated and controls the power transmission process on the basis of a detection result thereof. Consequently, it is possible to determine not only whether or not a foreign substance is present in a power transmission region but also determines whether or not the foreign substance influences wireless power transmission with high accuracy, and thus reliability of the wireless power transmission system can be improved.

Claim (Index 18):
The control method according to  claim 17 ,\n further comprising: receiving information, regarding an amount of reception power which is received, at the power transmission device, and calculating a difference between the amount of reception power and an amount of transmission power which is transmitted from the power transmission device on the basis of the information regarding the reception power, transmitted from the power reception device, and determining the presence or absence of a foreign substance influencing wireless power transmission on the basis of the difference and the deviation information.
