PROBLEM TO BE SOLVED: To provide a biodegradable laminated film having printability, lamination strength and fusion sealing strength without damaging flexibility, concealability, decorative properties and ultraviolet cutting properties. SOLUTION: The biodegrable laminated film is constituted by laminating a coating layer (II), which is composed of 98-35 mass% of an aliphatic polyester copolymer (A) composed of an aliphatic dicarboxylic acid component (a1), an aliphatic dihydroxy compound component (a2) and a difunctional aliphatic hydroxycarboxylic acid component (a3) and 2-65 mass% of an aliphatic/aromatic polyester (B) composed of 20-95 mol% of an aliphatic dicarboxylic acid component (b1), 80-5 mol% of an aromatic dicarboxylic acid component (b2) and an aliphatic dihydroxy compound component (b3), at least on one side of a base material layer (I) of an aliphatic polyester composed of 100 pts.mass of the sum total of 98-35 mass% of the copolymer (A) and 2-65 mass% of the polyester (B) and 3-20 pts.mass of an inorganic filler (C).
