Abstract
According to one embodiment, an inspection device includes a transmitter, a receiver, and a supporter. The transmitter is configured to transmit a first ultrasonic wave including burst waves having a first period Tp. The receiver on which the first ultrasonic wave is incident is configured to output a signal corresponding to the incident first ultrasonic wave. The supporter is provided between the transmitter and the receiver. The supporter is configured to support an inspection object. The first period Tp (s), a distance Dx (m), and a velocity vx (m/s) satisfy 2Dx/((n+1)·vx)<Tp<2Dx/(n·vx). n is 1 or 2. The distance Dx is a shorter distance of first and second distances. The first distance is a distance along a first direction between the transmitter and the supporter. The second distance is a distance along the first direction between the supporter and the receiver.
