<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a sheet joint body for manufacturing the sheet joint body improved in joint quality. <P>SOLUTION: The method of manufacturing a sheet joint body 1 for manufacturing the sheet joint body 1 with the mutual abutting interface part of resin sheets being welded and joined by laminating the resin sheets 1a, 1b to form a laminate and irradiating the laminate 1 with laser beams 4a from the back face side of one of the laminated resin sheets, is characterized in that a support material 2 with elasticity to have the amount of compressive strain of 10-500 μm at 5 MPa pressurization is allowed to abut on the back face side of the other resin sheet and that irradiation of the laser beams is carried out in a state of pressurizing one resin sheet toward the other resin sheet at a pressure of 0.1-100 kgf/cm<SP>2</SP>. <P>COPYRIGHT: (C)2010,JPO&INPIT |
