A molding material and a molded article for laser welding are provided, which comprise a thermoplastic resin (A) comprising a rubber-reinforced resin (A1) obtained by polymerizing a vinyl monomer in a presence of a rubber-like polymer (a), or a composition (A2) of the rubber-reinforced resin (A1) and a (co)polymer (b) of a vinyl monomer, and which have a light transmittance at a wavelength of 808 nm in a range of 5% or higher when molded into a 4 mm-thick sample piece. The rubber-like polymer (a) dispersed in the thermoplastic resin (A) preferably has a weight average particle size of 50 to 220 nm, and preferably comprises particles of 300 nm or larger in diameter in an amount of 0 to 20 wt % relative to 100 wt % of the component (a). A laser light can transmit the molding material and the molded article, and allow the molding material and the molded article to be laser-welded with various resin moldings.
