ABSTRACT:
It is an object of the present invention to provide a laser-welded article that workpieces prepared simply can be easily unified by laser in one laser welding process without using complicated processes. Moreover, the laser-welded article has sufficient welding strength of the molded workpieces, and does not damage the resin property.The laser-welded article comprises:an integral construction of a single weakly laser-absorptive molded workpiece or plural weakly laser-absorptive molded workpieces, which is welded by exothermic through irradiating laser under butting at least a part of edge portions thereof, wherein the workpiece or the workpieces include a thermoplastic resin and a weakly laser absorbent to have an absorbance: a ranging from 0.07 to 3.0, and have abilities of absorbing at least partial beam of the laser and transmitting other partial beam of the laser.
