Zusammenfassung:	According to an embodiment of the present invention, provided is a wireless power transmission method which can minimize power waste. The wireless power transmission method comprises the steps of: transmitting a first detection signal; determining whether a response signal for the detection signal is received; if the response signal is not received, stopping the transmission of the first detection signal and transmitting a second detection signal; measuring a state value of a wireless power transmission coil; and setting the state value as a reference value for determining whether there is an object. 실시 예에 따른 무선 전력 송신 방법은 제 1 감지 신호를 전송하는 단계; 상기 감지 신호에 대한 응답 신호의 수신 여부를 판단하는 단계; 상기 응답 신호가 수신되지 않으면, 상기 제 1 감지 신호의 전송을 중단하고 제 2 감지 신호를 전송하는 단계; 무선 전력 송신 코일의 상태 값을 측정하는 단계; 및 상기 상태 값을 물체의 존재 여부를 판단하기 위한 기준 값으로 설정하는 단계를 포함한다.
