PROBLEM TO BE SOLVED: To provide an optical axis measuring method of spherical optical uniaxial crystal that easily measures the optical axis itself and facilitates the subsequent detection of the equatorial plane and processing/assembling. SOLUTION: This optical axis azimuth measuring apparatus is an optical axis azimuth measuring apparatus of a spherical member formed of single crystal of optical uniaxial crystal having double refraction. The reflection optical axis azimuth measuring apparatus comprises a light irradiating means for irradiating the spherical member with light via a polarizer 102, and an isogyre observing means for observing an isogyre constituted, via an analyzer 107 having a cross nicol relation with the polarizer 102, by the light that comes into the spherical member 11, is reflected on the bottom surface of the spherical member 11, and goes out of the spherical member 11.
