PROBLEM TO BE SOLVED: To obtain a polypropylene-based resin film which has high heat-distortion resistance at a high temperature, for example, has excellent processing suitability such as adhesive processing, etc., a few fish eyes, improved handleability of film in spite of substantially not containing a lubricant and an antiblocking agent, for example, suitable as a substrate film of a protective film. SOLUTION: The polypropylene-based resin film comprises a composition obtained by mixing, based on 100 pts.mass of a polypropylene-based resin composition containing≥3.0 mass% of a rubber component, 0.01-0.1 pt.mass of a crystal nucleating agent, 0.01-0.1 pt.mass of an acrylate-based antioxidant and 0.05-1.0 pt.mass of at least one kind selected from a phosphorus-based antioxidant and a phenol-based antioxidant.
