PROBLEM TO BE SOLVED: To provide a decorative adhesive sheet which has little environmental load when burned or discarded, has a sufficient tear strength, is excellent in applicability to a curved surface etc. and is excellent in weather resistance. SOLUTION: The adhesive sheet has an adhesive layer stacked on a substrate sheet, wherein the substrate sheet comprises an acrylic urethane copolymer obtained by reacting a vinyl compound containing at least one (meth)acrylate with a high-molecular linear polyurethane prepolymer having ethylenically unsaturated double bond groups at both ends. The high-molecular linear polyurethane prepolymer has a weight average molecular weight within the range of 10,000 to 1,000,000, and the weight ratio of the high-molecular linear polyurethane prepolymer to the vinyl compound is within the range of 60:40 to 30:70.
