Zusammenfassung:	PURPOSE:To form a resin part in a complicated shape with good productivity by forming separately said resin part and a resin part to be welded and to be mounted with said resin part, and thermally welding said resin part and said resin part to be welded. CONSTITUTION:In forming an intake pipe, a main body 21 and a flange portion 22 of the pipe are formed separately by, for example, injection molding or blow molding. The main body 21 and the flange portion 22 are thermally welded to be united. At this time, it is preferable that one surface of the main body 21 is thermally welded to one surface of the flange portion 22. Accordingly, the resin parts can be integrally formed with a favorable strength of thermal welding, and therefore the resin parts can be easily formed into a complicated shape even when a plastic hard to mold is employed therefor. Thus, the resin parts can be manufactured with reduced cost, and at the same time, the productivity can be improved.
