Abstract
A method for laser welding comprises: forming a laser-transmissible resin workpiece 1 exhibiting whitish hue of white, gray or tint color out of a resin composition which includes 100 parts by weight of a thermoplastic resin and 0.1 to 2 parts by weight of white pigment having 2 to 2.8 of reflectance, piling a resin workpiece 2 being at least partly capable of laser-absorption onto the laser-transmissible resin workpiece 1, and then irradiating a laser beam 3 thereto to weld them thermally.
