摘要： A molded article such as a resin window or a lamp lens for vehicles which is formed from a polycarbonate and excellent in heat resistance, weather resistance, low water absorption, surface hardness and low-temperature impact properties. The molded article is formed from a polycarbonate which contains a unit (A) represented by the following formula (A) in an amount of 50 mol% or more based on the total of all recurring units and has a maximum impact energy of 20 J or more in a high-speed surface impact test based on ASTM D3763 in a -20°C environment and a brittle fracture rate of 50 % or less.
