摘要： A resin tube is prepared. Further, a formation tool having a pressing surface and a projection that projects from the pressing surface and is insertable into the resin tube is prepared. The projection of the formation tool is inserted from an end of the resin tube into the resin tube. The pressing surface of the formation tool is pressed against an end surface of the resin tube. Thermal energy is applied to the end of the resin tube, whereby a shape of the pressing surface of the formation tool is transferred to the end surface of the resin tube, and the end of the resin tube is formed into a flange shape.
