PROBLEM TO BE SOLVED: To integrally form a joint part for connecting a partner connection pipe member of a fluoroplastic resin container. SOLUTION: A resin block 30, which becomes a joint part 3 by the drilling processing and flaring processing of a post-process and is equipped with a chuck grasping part 32 at the time of drilling processing, is preliminarily held to a rotary mold 6, and a container body part 2 molded at the time of rotary molding and the resin block 30 are integrally fused. After mold opening, the chuck grasping part 32 on the resin block 30 is grasped to form the resin block 30 into a cylindrical body 33 by cutting processing and a flange 35 is subsequently formed to the leading end of the cylindrical body by flaring processing.
