PROBLEM TO BE SOLVED: To provide a molding method of a flanged cylindrical body having a flange part integrally formed thereto, and a mold therefor. SOLUTION: A slide mold 2 is reciprocally slid in a mold opened state to be clamped not only to inject a primary molding resin material in one ring-shaped cavity 41 for primary molding to mold flange part W1 but also to inject a secondary molding resin material in the cavity 42 for secondary molding to which a molded flange part W1 is set to mold the flanged cylindrical body integrated with the flange part W1. Thereafter, the mold is opened, the flanged cylindrical body is taken out in the state set to a movable mold 3, the slide mold 2 is allowed to reciprocally slide to be clamped, the primary molding resin material is injected in the other ring-shaped molding cavity 41a to mold the flange part W1 and a secondary molding resin material is injected in the secondary molding cavity 42 to which the molded flange part W1 is set to mold the flanged cylindrical body W integrated with the flange part W1.
