PROBLEM TO BE SOLVED: To provide an impact inspection device capable of acquiring a homogeneous inspection result without depending on experience or sensitivity of an inspector. SOLUTION: This impact inspection device 1 is characterized by having sensors 6 for measuring vibration excited in an inspection object, a base member 2 having one or more sensors mounted thereon, for supporting the inspection object from below, a frequency analysis part 12 for acquiring frequency spectrum of a signal measured by the sensors, and a discrimination part 14 for discriminating the inspection object by comparing a dominant frequency of the frequency spectrum acquired by the frequency analysis part with a dominant frequency of a sound inspection object.
