Abstract
A first imaging unit images a first region to be subjected to mirror finish treatment of an inspection region of a surface of the object. A second imaging unit images a second region not to be subjected to the mirror finish treatment of the inspection region of the surface of the object. An inspection unit inspects a form of the first region based on a first picked-up image taken by the first imaging unit, and a form of the second region based on a second picked-up image taken by the second imaging unit. During imaging, a holder holds the object so as to have a positional relationship in which the first region has a normal along a first direction rather than a second direction.
