PROBLEM TO BE SOLVED: To provide an adhesive sheet with a protection film which can prevent occurrence of roll aberration when wound up into a roll, and does not cause resin peeling when the protection film is peeled in an auto cutter device.SOLUTION: An adhesive sheet with a protection film has an adhesive sheet consisting of a base having first and second surfaces and a resin composition layer joining with the second surface of the base, and a protection film having first and second surfaces, with the second surface provided to bond to the resin composition layer of the adhesive sheet. Arithmetic mean roughness (Ra) of the first surface of the protection film is not less than 100 nm, and arithmetic mean roughness (Ra) of the second surface of the protection film is not less than 100 nm.SELECTED DRAWING: Figure 1 |
