The invention relates to a foreign substance detection device, a power supply device, an electric power reception device and an electric power transmission system. The detector (120) of the foreign substance detection device (100) determines the presence or absence of a foreign substance on the basis of the results of comparison between a value for comparison, based on an output value from a sensor, and threshold values. The threshold values include a first threshold value and a second threshold value that is greater than the first threshold value. The detector (120) determines that the foreign substance is present when the number of times at which the value for comparison exceeds the first threshold value reaches the first number of times, and determines that the foreign substance is present when the number of times at which the value for comparison exceeds the second threshold value reaches the second number of times smaller than the first number of times.

    本发明涉及异物检测装置、供电装置、受电装置及电力传输系统。在无线电力传输中以高精度快速地检测异物。异物检测装置(100)的检测部(120)基于根据传感器的输出值的比较对象值和阈值的比较结果,判别异物的有无。上述阈值包含第一阈值和比第一阈值大的第二阈值。检测部(120)在比较对象值超过第一阈值的次数达到第一次数的情况下,判别为有异物,在比较对象值超过第二阈值的次数达到比第一次数少的第二次数的情况下,判别为有异物。
