Abstract
An optical pickup device-holding container, which is formed from a resin composition comprising a poly(arylene sulfide) (A) and an inorganic filler (B) and having a thermal conductivity of at least 1 W/mK; and an optical pickup device in which at least a light source, an objective lens and a light-receiving part are held in the holding container.
Claims8
An optical pickup device-holding container for holding an optical pickup device equipped with at least a light source, an objective lens and a light-receiving part, wherein the holding container is formed of a resin composition comprising
- 100 parts by weight of a poly(arylene sulfide) having a melt viscosity of from 3 to 140 Pa·s as measured at 310° C. and a shear rate of 1,200/sec,
- 80 to 150 parts by weight of at least one metal oxide powder selected from the group consisting of spherical alumina having an average particle size of from 8 to 50 μm and ferrite compounds having an average particle size of from 2 to 50 μm, and
- 20 to 300 parts by weight of a fibrous filler selected from the group consisting of glass fibers, carbon fibers, wollastonite, potassium titanate and aluminum borate,
- the resin composition having a thermal conductivity of at least 1 W/mK.
