PROBLEM TO BE SOLVED: To provide an optical characteristic measuring instrument which reduces the restriction of a measuring target, can quantitatively detect the double refraction distribution of the measuring target and is suitable for analyzing a biosample or the like in a face state, and also to provide an optical characteristic measuring method. SOLUTION: The optical characteristic measuring instrument includes an optical system 10, a light intensity data acquiring part 40 for acquiring the light intensity data of measuring light and an operational processing part 60. The optical system 10 is constituted so that the light emitted from a light source is thrown on a sample 100 through a polarizer 22, a first 1/2 wavelength plate 24, a 1/4 wavelength plate 26 and a second 1/2 wavelength plate 28 and also thrown on a light detection part 14 through an analyzer 30, and the first and second 1/2 wavelength plates and the analyzer are constituted in a rotatable manner. In the light intensity data acquiring part, the light intensity data of a plurality of measuring lights are acquired. In the operational processing part, at least one of the double diffraction phase difference and main axis azimuth of the sample is calculated on the basis of a theoretical formula of the intensity of measuring light and the light intensity data of measuring light.
