    摘要: According to one embodiment, an inspection device includes a transmitter, a receiver, a feeder, and a processor. The transmitter emits an ultrasonic wave. The feeder causes an inspection object to move relative to the transmitter and the receiver in a space between the transmitter and the receiver. The processor processes a received signal corresponding to the ultrasonic wave obtained by the receiver. In a first state in which the inspection object includes a first region and a second region, the first region includes a foreign object, and the second region does not include the foreign object. The received signal includes a first signal level in a first interval, a second signal level in a second interval, and a third signal level in a third interval. The processor detects the foreign object by detecting at least one extreme value occurring in the received signal in a fourth interval.
