PROBLEM TO BE SOLVED: To provide a biaxially oriented self-adhesive protective film excellent in flexibility, transparency, anti-blocking property and adhesive property while easily peeled off if necessary, suitable for production of a wide product, and capable of being manufactured cleanly at a low cost. SOLUTION: The biaxially oriented self-adhesive protective film comprising at least three-layer laminated film composed of a self-adhesive layer/an intermediate layer/a non-adhesive layer in the order. The intermediate layer comprises a specified propylene based resin composition (A) of 50-100 wt.% and a propylene homopolymer (B) of 50-0 wt.%, the self-adhesive layer comprises a hydrogenated styrene based elastomer (C) of 50-70 wt.% and a specified propylene-α-olefine random copolymer (D) of 50-30 wt.%, and the non-adhesive layer is a component satisfying a specified requirement.
