PROBLEM TO BE SOLVED: To provide a surface protection film which is able to satisfactorily protect an adherend having a projection while keeping good adhesion therewith and has an adequate anchoring force against an intermediate layer made of an acrylic resin. SOLUTION: This surface protection film comprises a support made of a polyethylene film or the like, and a self-adhesive layer which is formed on one side of the support and is made of a block copolymer composition, which comprises a triblock copolymer including one intermediate polymer block derived from a conjugated diene compound such as isoprene or the like and two terminal polymer blocks derived from a vinyl aromatic compound such as styrene or the like in such a way that the content of the vinyl aromatic compound is not less than 14% in terms of styrene and the content of the triblock copolymer is not less than 40%, and to which an additive such as a tackifier or the like is added, if necessary. |
