PROBLEM TO BE SOLVED: To provide a method to manufacture a synthetic resin-made tank with quality anchor seats at low costs. SOLUTION: A tank body 1b and a plurality of anchor seats 2a are made separately from the same kind of synthetic resin. Then, butt surfaces between the tank body 1b and respective anchor seats 2a are heated with a heater 22 to be melted, and the tank body 1b and each anchor seat 2a is butted each other. Through this work, a plurality of the anchor seats 2a are welded to the lower end outer peripheral surface of the tank body 1b. Thus, the anchor seats are constructed using a simpler mold and without using a chemical-corrosive material. COPYRIGHT: (C)2004,JPO&NCIPI
