<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of resin accumulating piping constituted so as to certainly and easily welding laminated resin plates so as not to cause the leak of a fluid in a flow channel when the laminated resin plates are welded to form the flow channel between the resin plates, and the resin accumulating piping. <P>SOLUTION: Grooves 4a and 4b, which constitute the flow channel, are provided at least one resin plate 2 of the resin plates 2 and 3 to be laminated and metal wires 5a and 5b continuously arranged along the outer edges of the grooves 4a and 4b are arranged while the resin plates 2 and 3 are laminated so as to hold the metal wires 5a and 5b and the resin provided along the grooves 4a and 4b of the laminated resin plates 2 and 3 by heating the metal wires 5a and 5b to mutually weld the resin plates 2 and 3. <P>COPYRIGHT: (C)2007,JPO&INPIT |
