PROBLEM TO BE SOLVED: To provide a laminated stretched film which is reduced in peeling with time between a base material for decorative sheet and a laminate including a base material for decorative sheet and a transparent resin layer provided on an upper layer of a printing layer while having easy peelability with the laminate, a base material for decorative sheet, a decorative sheet and a decorative plate. SOLUTION: A base material 6 is a uniaxially or biaxially laminated stretched film in which a main component of a resin material is made of polypropylene, and has a plurality of layers (number n of layers≥2, n is an integer) in which the main component of the resin material is made of a polypropylene-based resin. When an uppermost layer positioned on the outermost surface among the plurality of layers is defined as a surface layer 6-1, and layers other than the surface layer 6-1 among the plurality of layers are defined as core layers 6-2 to 6-(n-1), Marten hardness of the surface layer 6-1 is less than 20 N/mm 2 or 120 N/mm2 or more, or a peak intensity ratio in Raman spectroscopy is 6.0 or more and less than 50.0.SELECTED DRAWING: Figure 1
