PROBLEM TO BE SOLVED: To provide a biodegradable sheet, which has good moldability, does not require a high mold temperature, and affords molded articles of good heat resistance. SOLUTION: The method for molding the biodegradable sheet comprises; preliminarily crystallizing a sheet of a resin composition, in which 75 to 25 wt.% of a polylactic acid-based resin and 25 to 75 wt.% of a polyester are blended to make 100 wt.% in total; and molding at a temperature, higher than the melting point of the aliphatic polyester and lower than the melting point of the polylactic acid-based resin; wherein the polyester has a glass transition temperature of 0°C or lower and a melting point of, higher than the glass transition temperature and not higher than the melting point of the polylactic acid-based resin.
