PROBLEM TO BE SOLVED: To provide a matte polylactic acid type biaxially stretched laminated film high in haze and having low glossiness and a matte feeling. SOLUTION: In the polylactic acid type biaxially stretched laminated film containing a layer A comprising a polylactic acid polymer (A) and a layer B comprising a biodegradable resin (B), at least one of the outer layers of the laminated film is the layer B and the biodegradable resin (B) is constituted of 60-90 mass% of a polylactic acid polymer (C) and 10-40 mass% of a biodegradable polyester (D). The biodegradable polyester (D) comprises at least one kind of a polymer selected from an aliphatic polyester, an alaromatic copolyester and a polyester carbonate. The haze of the laminated film is 50% or above and the glossiness thereof is 10% or below. This polylactic acid type biaxially stretched laminated film can be suitably used as a food packaging material such as a confectionery bag or the like, a packaging material for medicines, a packaging material for use in overlapping suitable for the individual or integrated packaging of a magnetic disk or the like, a laminated film with paper or the like.
