PROBLEM TO BE SOLVED: To provide a polypropylene film which is suitable for packaging, a capacitor, etc., and excellent in recyclability. SOLUTION: In the polypropylene film, at least on one side of a polypropylene resin layer (B layer) at least 90% in mesopentad fraction (mmmm), a polypropylene resin layer (A layer) having the ratio Rmax/Ra between the largest surface roughness Rmax and center line average surface roughness Ra of 8-16, the number of projections SPc per standard area of at least 10 projections/0.1 mm2, and a crystal fusion temperature of at least 150 deg.C is laminated.
