PROBLEM TO BE SOLVED: To provide a propylene resin composition for welding excellent in welding properties in a secondary processing stage, and to provide a method for producing the same.SOLUTION: The composition includes 35 to 95 mass% of a propylene polymer (A), 1 to 30 mass% of an olefinic elastomer and/or a vinyl aromatic compound-containing elastomer (B), and 1 to 35 mass% of an inorganic filler (C). The composition has an isothermal crystallization rate at 140°C of 100 seconds or more and a moisture content of 350 ppm or less. The propylene polymer (A) is a polymerization material of a propylene homopolymer component (I) and a propylene copolymer component (II) having an intrinsic viscosity ([η]) as measured in tetralin at 135°C of 2.5 to 10 dl/g. |
