Abstract
An inspection device is adapted for inspecting whether or not there is a foreign matter or dirt adhered to a surface of a workpiece or whether or not there is a scratch on the surface of the workpiece. A first polarizing plate having a polarizing axis in a first direction is attached to an open window of the cover part, and a second polarizing plate having a polarizing axis in a second direction orthogonal to the first direction is attached to the open window so as to open and close. In a state where the second polarizing plate is closed, the second polarizing plate overlaps the first polarizing plate. In a state where the second polarizing plate is open, the first polarizing plate and the second polarizing plate are present on a straight line connecting the outside light source and the fuel cell.
