To obtain a surface protecting film capable of preventing a load of stacked adherends from collapsing when temporarily bonded to the adherends and further tacking when compressed and facilitating the takeout by specifying a static friction coefficient of mutual surfaces of polyolefin-based resin substrate films having a tacky layer formed on one surface.

This surface protecting film is obtained by composing a substrate film thereof temporarily bonded to a surface such as a fancy plywood, a metallic plate or a coated steel sheet of a polyolefin-based resin having 0.4-0.8 static frictional coefficient of mutual substrate films. A tacky agent (an ethylene- vinyl acetate copolymer, etc.) is provided in a layer form on one surface of the substrate film.
