<P>PROBLEM TO BE SOLVED: To provide a laser welding method capable of closely welding the mutual joining parts of resin members without depending on the shapes of the resin members. <P>SOLUTION: The laser welding method for welding at least two resin members W1 and W2 using a laser beam has an arranging process for mutually combining the resin members W1 and W2 to arrange them in a container 22 of which the wall is partially formed of a stretchable light transmitting sheet 28, a closely bonding process for applying pressure uniform per a unit area to the resin members W1 and W2 from the light transmitting sheet 28 by internally evacuating the container 22 to closely bond the mutual joining parts Wc of the resin members W1 and W2, and a welding process for mutually welding the resin members W1 and W2 by irradiating the joining parts Wc with the laser beam through the light transmitting sheet 28. <P>COPYRIGHT: (C)2008,JPO&INPIT |
