Abstract: PROBLEM TO BE SOLVED: To obtain the optical axis of a phase contrast plate constituting a composite plate simply, with high accuracy and small variations by workers by placing the sample of a composite plate on a reference polarizing plate and confirming the tonality of the part in which both are overlapped each other. SOLUTION: The sample of a composite plate 5 in which a polarizing plate and a phase contrast plate are laminated is placed on a reference polarizing plate 1 whose optical axis 2 is parallel or orthogonal with respect to a reference line 3 so that a part 9 where the sample of the composit plate 5 and the reference polarizing plate 1 are overlapped each other becomes a neutral color. When this part 9 becomes the neutral color, the direction of the optical axis 6 of the sample of the composite plate 5 is either a parallel direction or an orthogonal direction with respect to the reference line 3.  Whether the direction of the optical axis 6 is the parallel direction or the orthogonal direction with respect to the reference line 3 is, for example, judged by comparing the tonality at the time the sample of the composite plate 5 is revolved a little on the polarizing plate 2 with the tonality of the sample of a composite plate 5 whose direction of an optical axis 6 is preliminarily known and which is to become a standard. Moreover, the angle of the optical axis 6 can be measured with a preliminarily provided protractor 7.
