The objective of the present invention is to provide a polylactic acid sheet having superior moldability, transparency, and heat resistance. The polylactic acid sheet is non-oriented and has an A layer having a polylactic acid resin as the main constituent (hereinafter, the polylactic acid resin comprising the main constituent of the A layer is referred to as polylactic acid resin A), the polylactic acid resin A having a melting point of at least 190°C and less than 230°C when measured under the belowmentioned conditions (1). Conditions (1): When measuring DSC, in a first heating step, heating is performed from 30°C to 250°C at a rate of temperature increase of 20°C/minute, after which cooling is performed to 30°C at a rate of temperature decrease of 20°C/minute, and further heating is performed from 30°C to 250°C in a second heating step at a rate of temperature increase of 20°C/minute, at which point the melting point is measured. |
