An inspection system is provided that includes a microscope that scans a sample with a beam that is an incident electron beam, and an image processing device that controls the microscope. The image processing device performs: an acquisition process of acquiring a plurality of images relating to brightness based on an amount of a signal electron detected from the sample a result of controlling the microscope according to a s and irradiating the sample with the beam, the plurality of image acquisition condition being multiple combinations of different irradiation amounts of the beam per unit length; a first generation process of generating a plurality of actually measured profiles that show a relationship between an irradiation position of the beam in the sample and the brightness of the sample, based on the plurality of images acquired in the acquisition process; and an output process of outputting an electrical contact characteristic of the sample based on the plurality of actually measured profiles generated in the first generation process.
