An underlay film for cutting and a manufacturing method thereof are provided to restrain dust from being generated or stuck on an optical or electronic part by using a polypropylene film having a polymer anti-static layer as the underlay film during a cutting process of the optical or electronic part. An underlay film for cutting has a laminated film formed by laminating a polypropylene resin layer(C) containing a polymer anti-static agent, on at least one surface of a polypropylene resin film(A). The surface resistance of the polypropylene resin layer is below 10^12Ф/cm. The underlay film is used as an underlay in cutting a planar optical or electronic part. The thickness of the polypropylene resin film is 150~1200 micron meters and thickness of the polypropylene resin layer is 2~100 micron meters.
