A polyphenylene sulfide resin composition which comprises 100 parts by weight of a polyphenylene sulfide resin (A) and, compounded therewith, 1 to 100 parts by weight of glass fibers (B) having a single-fiber diameter of 12 mum or lager and has a crystallization temperature during cooling of 205°C or lower. Also provided is a polyphenylene sulfide resin composition which comprises 100 parts by weight of a polyphenylene sulfide resin (A) and, compounded therewith, 1 to 100 parts by weight of glass fibers (B) having a single-fiber diameter of 10 to 12 mum, excluding 12 mum, has a crystallization temperature during cooling of 205°C or lower and a chloroform-extractable content of 0.5 wt.% or lower, and gives a 2 mm-thick molding which has a transmittance of 15% or higher for laser light having a wavelength of 940 nm and a heat distortion temperature of 230°C or higher under a load of 1.82 MPa.
