Provided is an outer joint member for a fixed type constant velocity universal joint, the outer joint member contributing to reduction of the number of man-hours through reduction of the number of post processes after a forging process, and to an increase in yield, and reduction of manufacturing cost. The outer joint member for a fixed type constant velocity universal joint includes a cup section (16) and a shaft section (18) extending in an axial direction from a bottom portion of the cup section (16). The outer joint member is made of machine-structural carbon steel. The following portions of the outer joint member are finished by cold forging: track grooves (12); radially inner spherical-surface portions (14a); a cup-inlet chamfer (12b); track chamfers (12c); track-inlet chamfers (12a); a part except for a boot fixing portion (19) on a radially outer surface of the cup section (16); and a center hole (13) at an end surface (18a) of the shaft section (18).
