PROBLEM TO BE SOLVED: To provide an industrially available film-form molded useful product prepared by molding an aliphatic polyester-based biodegradable resin. SOLUTION: The biodegradable resin film-form molded product is prepared by molding an aliphatic polyester-based biodegradable resin composition composed of an aliphatic polyester copolymer (a) having a weight average molecular weight of 40,000 or over and being composed of a repetition unit (P) represented by a general formula molecular chain -(-CO-R1-COO-R2-O-)- (1) wherein R1 represents a bivalent 1-12C aliphatic group and R2 represents a bivalent 2-12C aliphatic group, and a repetition unit (Q) represented by a general formula -(-CO-R3-O-)- (2) wherein R3 represents a 1-10C bivalent aliphatic group, and optionally another biodegradable resin (b).
