Disclosed is a polypropylene resin film for surface protection, which has excellent thermal dimensional stability, planarity, impact resistance and bonding workability, while being reduced in fish eyes. The polypropylene resin film for surface protection is free from wrinkles or sags when the film is rolled into a roll. The polypropylene resin film is suitable, for example, for a base film of a protective film. Also disclosed is a protective film which is obtained by providing the polypropylene resin film for surface protection with an adhesive layer. Specifically disclosed is a polypropylene resin film for surface protection, which is substantially composed of a polypropylene resin and is characterized by having a xylene-soluble content at 20 DEG C of more than 9% but less than 15%, a crystal nucleator content of not more than 100 ppm, a film thickness variation in the width direction of not less than 1% but not more than 10%, a coefficient of kinetic friction of not more than 1.0, and a tensile modulus of elasticity of not less than 500 MPa but not more than 900 MPa.
