The detector of a foreign substance detection device 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 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.
