PURPOSE: To obtain an adhesive film for surface protection excellent in cutting performance with a cutter and workability when applied on a base material made of an olefinic resin. CONSTITUTION: This adhesive film for surface protection has an adhesive layer on one face of a base material. The base material is composed of A layer and B layer, and the A layer contains hard segments and soft segments, whose compositions are shown below, and the B layer contains a polyolefinic resin. The hard segment consists of a polypropylene. The soft segment is a resin consisting of at least one selected from among (1) a propylene-ethylene copolymer, (2) a copolymer of propylene withα-olefin expressed by the formula CH2 =CHR (R is a 2-8C aliphatic group or an aromatic group) and (3) a copolymer of propylene with a diene compound.
