    • PROBLEM TO BE SOLVED: To provide a laser ray transmitting colored resin composition excellent in molding accuracy, good in molded product appearance and gloss, capable of preventing or effectively reducing the gap between the materials to be welded in the case of a molded product used for laser welding, and good in heat resistance and fastness, and to provide the laser ray transmitting material excellent in dimension stability and shape stability and capable of preventing or effectively reducing the gap between the materials to be welded when used for laser welding.
      SOLUTION: The laser ray transmitting colored resin composition comprises a polyphenylene sulfide resin and a colorant having an endothermic peak between 200°C and 300°C as determined by TG/DTA thermal analysis, wherein the difference T
      C -T
      N between the crystallization point T
      C of the laser ray transmitting colored resin composition and the crystallization point TN of the same composition as the composition except for not containing the aforementioned colorant, is not less than 0°C as determined by DSC thermal analysis. The laser ray transmitting material is made of the laser ray transmitting colored resin composition, and has one exothermic energy peak and one endothermic energy peak as determined by DSC thermal analysis.
