Abstract
A polyarylene sulfide resin composition having an excellent fluidability and a good moldability is disclosed. The resin composition is useful as a material for an optical pick-up part which has a high reliability and a high tenacity and does not generate deviation of an optical axis with changes in environmental conditions such as temperature and humidity. The polyarylene sulfide resin composition comprises, as main components, a polyarylene sulfide resin, a fibrous filler and a particulate filler, and, optionally, a silane coupling agent and an alicyclic hydrocarbon.
