PURPOSE: To improve a reliablity and a high toughness to prevent an occurrence of a shift of an optical axis by an environmental change in temperature, humidity, and the like by molding a resin composition prepared by adding a filler, a silane coupling agent, a specific alicyclic hydrocarbon, and the like to a polyarylene sulfide resin.
CONSTITUTION: As a polyarylene sulfide resin, a polyphenylene sulfide and the copolymer thereof are typically used. As a filler to be compounded with the resin, a fibrous filler, such as glass fiber, carbon fiber, Tyranno fiber, and potassium titanate fiber, and a particle filler, such as aluminum borate and silca, can be used. As a silane coupling agent to be compounded, a vinyl tris(β- methoxy)silane and the like can be used. Furthermore, as an alicyclic hydrocarbon, a hydrogenated compound can be used, and a compound represented by a formula is preferably used. In the formula, R1, R2, and R3 are alkyl group, and (n) is an integer.
