<P>PROBLEM TO BE SOLVED: To provide a method for joining sheet members which joins the same satisfactorily using a laser beam even when the sheet members of different kinds of thermoplastic resins and a join member are joined to each other or even when the sheet members one of which is composed of a non-melting resin such as a thermosetting resin and the join member are joined to each other, and to provide a joined sheet body. <P>SOLUTION: In the method for joining the sheet members 10 and 20 by joining the ends 11 and 12 of the sheet members 10 and 20 via the join member 30, either one of the sheet members 10 and 20 and the join member 30 is composed of a thermoplastic resin having a storage modulus (E') of less than 1.0×10<SP>6</SP>Pa at 170°C. The sheet members 10 and 20 and the join member 30 are brought into contact with each other, and a laser beam R is irradiated on the contact part to join them. The contact angle at the laser beam R radiation part of the sheet members 10 and 20 and the join member 30 is less than 100 degrees. <P>COPYRIGHT: (C)2011,JPO&INPIT |
