Abstract
An object of the present invention is to provide a thermoplastic resin composition, an extruded sheet and a copper clad laminate excellent in processability such as extrusion processability and injection moldabilities, solder heat resistance and mechanical properties such as bending properties, durability and drilling processability and satisfying low dielectric loss necessary for high frequency band telecommunication parts. The present invention relates to a shaped article composed of a resin composition prepared by adding a specific graphite to a resin composition containing (a) a polyarylene sulfide resin and (b) a polyphenylene ether resin as main components, and a multilayer extruded sheet comprising an inner layer of a resin composition prepared by adding a metal oxide to a resin composition containing (a) a polyarylene sulfide resin and (b) a polyphenylene ether resin as main components and an outer layer of a resin composition to which no metal oxide is added. The present invention also relates to a copper-clad laminate prepared by stacking copper foil or copper plating on at least one side or both sides of the shaped article or the multilayer extruded sheet.
