PROBLEM TO BE SOLVED: To bond thermoplastic synthetic resin members to each other by irradiation with laser beams. SOLUTION: A bonding method by laser beams includes a process in which a transparent member 6 which is made of a thermoplastic synthetic resin and transmits prescribed laser beams is contacted with the end surface of an opaque member 5 which is made of a thermoplastic synthetic resin and transmits prescribed laser beams, a process in which a part where the transparent member 6 contacts the opaque member 5 is irradiated with laser beams to make the focus coincide from the transparent member 6 side with the use of a laser torch 1 which emits prescribed laser beams, and a process in which after the irradiation of laser beams, in the state of the contact part of the resin members 5, 6 and its periphery being softened, the resin members 5, 6 are pressed with a prescribed press means 2. |
