DECORATIVE SHEET

PROBLEM TO BE SOLVED: To prevent crack or blushing of a protective sheet at the time of V-grooving by constituting a sheet base material by olefin resin obtained by mixing high density polyethylene with thermoplastic elastomer and inorganic filler. SOLUTION: A sheet base material 2 of the decorative sheet 1 is constituted by olefin resin obtained by mixing high density polyethylene with thermoplastic elastomer and inorganic filler. The olefin resin for constituting the material 2 contains 10 to 60wt.% of the thermoplastic elastomer and 5 to 60wt.% of the filler so that the total content of the both is 70wt.% or less. The material 2 can be directly printed on its surface with decorative pattern 4 or directly coated with adhesive for adhering a protective sheet 3. When adhesive strength of printing ink or adhesive to the material 2 is more strengthened, an easily adhesive layer 5 is provided on a rear surface of the material 2.
