PROBLEM TO BE SOLVED: To provide an abnormality inspection method for inspecting a test object without complicating a device.SOLUTION: There is provided an abnormality inspection method including processes of: acquiring a vibration signal according to vibration of a rotor detected by a first sensor from the first sensor; executing an allophone inspection of the rotor on the basis of the vibration signal from the first sensor; calculating rotation speed of the rotor from the vibration signal from the first sensor; acquiring an AE signal according to AE to be generated in the rotor, detected by an AE sensor from the AE sensor; detecting a specific AE signal to be generated by rotation of the rotor on the basis of the rotation speed and the AE signal; executing an AE inspection of the rotor on the basis of the specific AE signal; and determining presence/absence of an abnormality of the rotor on the basis of results of the allophone inspection and the AE inspection. |
