Zusammenfassung:PROBLEM TO BE SOLVED: To provide an outside joint member for a constant velocity universal joint capable of extending operating life of cutting tools and reducing manufacturing costs. SOLUTION: This is the outside joint member for the constant velocity universal joint which has a plurality of ball track grooves 2 in the inside diameter surface 1. The spherical surface roughness in the inner most side from the axial center 15 of the inside diameter surface 1 is made rougher than the spherical surface roughness in the opening side from the axial center of the inside diameter surface 1. The spherical surface roughness in the inner most side from the axial center of the inside diameter surface 1 is made R2 and when the spherical surface roughness in the opening side from the axial center of the inside diameter surface 1 is made R1, R1
