PROBLEM TO BE SOLVED: To provide a polypropylene multilayer film which dispenses with a process for coating a release agent solution, from the surface of which a polydimethylsiloxane is scarcely detached and is excellent in releasing property from a pressure sensitive adhesive. SOLUTION: The polypropylene multilayer film comprises (A) a layer of a polypropylene, and (B) a layer of a releasing resin composition including 95-99.99 wt.% of an olefin polymer and 0.01-5 wt.% of polydimethylsiloxane having an epoxy group and/or an amino group, the functional group equivalent of which is 500 g/mol or grater and 50,000 g/mol or less.
