Abstract
Disclosed is an injection molded article made of a resin composition comprising 15 to 40% by mass of ultrahigh molecular weight polyethylene fibers, and 60 to 85% by mass of a thermoplastic resin having a melt flow rate of 70 to 500 g/10 min. measured at a temperature of 230° C. and a load of 21.2 N, and a fusion peak temperature lower than 160° C. measured with a differential scanning calorimeter, where the combined mass of the ultrahigh molecular weight polyethylene fibers and the thermoplastic resin is taken as 100% by mass, wherein the injection molded article satisfies the following requirements: the intrinsic volume resistivity is 1.0×10Ω·cm or more, the thermal conductivity is 1 W/m·K or more, and the specific gravity is 1.2 or less. The article is high in rigidity, impact resistance, electrically insulating property, and thermal conductivity.
