Abstract: [Problem] There is provided a goods inspection device making it possible to make a diagnosis easily for inspection function failure caused by dynamic behavior of goods attributed to a conveyance subsystem of an inspection line. [Solution] The goods inspection device 1 that inspects goods being carried on an inspection line includes a diagnosis unit 25c that diagnoses a conveyance subsystem of the inspection line, based on data of acceleration and angular velocity obtained with respect to respective axial directions from a test object 2 when the test object 2 having a motion sensor 12 to detect acceleration and angular velocity with respect to respective directions of three-dimensional axes is carried.
