A method of manufacturing an outer joint member of a constant velocity universal joint, the method comprising: joining a cup member; and a shaft member to form the outer joint member, wherein the cup member has a bottomed cylindrical shape that is opened at an end on one side in an axial direction, and comprises a cylindrical portion (12a1), a bottom portion (12a2), and a short shaft portion (12a3) protruding from the bottom portion (12a2) toward the other side in the axial direction, and the short shaft portion (12a3) has a solid shaft shape, and comprises an annular joining end surface at an end portion thereof, the shaft member has a solid shaft shape, and comprises a joining end surface at one end thereof, and the joining end surface of the cup member and the joining end surface of the shaft member are brought into abutment against each other and welded to form a welded portion having an annular shape, wherein the method comprising: forming the cup member by forging and interference of center segregation of the cup member with the welded portion is prevented for welding, characterized in that the forging comprising: upsetting a billet having a columnar shape successively in a plurality of stages; extruding the cylindrical portion (12a1) and the short shaft portion (12a3); and ironing the cylindrical portion (12a1), the welded portion is formed on the cup member side with respect to a bearing mounting surface of the shaft member, the bearing mounting surface is processed in advance before welding so that post-processing of the bearing mounting surface after welding can be omitted. joining a cup member; and a shaft member to form the outer joint member, wherein the cup member has a bottomed cylindrical shape that is opened at an end on one side in an axial direction, and comprises a cylindrical portion (12a1), a bottom portion (12a2), and a short shaft portion (12a3) protruding from the bottom portion (12a2) toward the other side in the axial direction, and the short shaft portion (12a3) has a solid shaft shape, and comprises an annular joining end surface at an end portion thereof, the shaft member has a solid shaft shape, and comprises a joining end surface at one end thereof, and the joining end surface of the cup member and the joining end surface of the shaft member are brought into abutment against each other and welded to form a welded portion having an annular shape, wherein the method comprising: forming the cup member by forging and interference of center segregation of the cup member with the welded portion is prevented for welding, characterized in that the forging comprising: upsetting a billet having a columnar shape successively in a plurality of stages; extruding the cylindrical portion (12a1) and the short shaft portion (12a3); and ironing the cylindrical portion (12a1), the welded portion is formed on the cup member side with respect to a bearing mounting surface of the shaft member, upsetting a billet having a columnar shape successively in a plurality of stages; extruding the cylindrical portion (12a1) and the short shaft portion (12a3); and ironing the cylindrical portion (12a1), the welded portion is formed on the cup member side with respect to a bearing mounting surface of the shaft member,
