Beschreibung
Zusammenfassung:	[Problem] Provide is the following: a polyphenylene sulfide resin composition the mechanical properties and dimensional stability of which are excellent, particularly the anisotropy of which is significantly reduced, and the expansion of which is reduced in moist heat treatment; and a molded article of the resin composition.[Solution] A polyphenylene sulfide resin composition comprising a blend of the following: 100 parts by weight of a polyphenylene sulfide resin (A); 100 to 250 parts by weight of a modified cross-section glass fiber (B); and 25 to 150 parts by weight of a non-fibrous inorganic filler (C) satisfying the following (C-a) and (C-b): (C-a) having a Mohs hardness of more than 2 and less than 4, and (C-b) having a melting point or softening point of 380°C or more; wherein the ratio X/Y of the mass X of the modified cross-section glass fiber (B) to the mass Y of the non-fibrous inorganic filler (C) is more than 1 and less than 7.
