PROBLEM TO BE SOLVED: To provide a residual stress inspection device for a light pervious substance dispensing with the rotation of an analyzer and capable of inspecting residual stress at a high speed. SOLUTION: Red, green and blue linearly polarized lights, which are passed through three polarizers 27, 28 and 29 arranged in different polarizing directions, are transmitted through an object 32 to be inspected and the analyzer 30. These red, green and blue lights are detected by a color CCD camera 31 and the polarizing characteristics of the object 32 to be inspected are calculated from the intensities of the respective color lights.
