ABSTRACT:
A molded article, particularly for optical use, formed of a thermoplastic saturated norbornene-based polymer composition including a thermoplastic saturated norbornene-based polymer excellent in heat resistance, etc., and a filler, the composition being capable of preventing cracks even when an insertion part having a linear expansion coefficient greatly different from that of the polymer is present and a thermal change occurs. The filler is selected from a fibrous filler and a combination of a fibrous filler with a powdery filler.
