<p>Disclosed is a polylactic acid based heat-resistant sheet suitable for molding. The polylactic acid based heat-resistant sheet containing 50 to 95% by mass of a polylactic acid and 5 to 50% by mass of a polylactic acid-based copolymer which contains 30 to 70 % by mole of a lactic acid component. The polylactic acid based heat-resistant sheet has a crystallization peak temperature of 60 to 120°C, a heat quantity of crystallization of 10 to 25 J/g, a melting point of 160°C or higher and a heat quantity of crystal fusion of 15 to 40 J/g, as measured with a differential scanning calorimeter at a temperature increase rate of 20°C/min.</p> |
