A release film that can be peeled off very easily from an adhesive surface. Moreover, the adhesive tape provided with such a peeling film is provided. A release film of the present invention is a release film having a porous film and a base film, wherein one of the outermost layers is the porous film and the other outermost layer is the base film. , a thickness of 0.1 mm to 3.0 mm, a density of 0.01g / cm 3 ~5.0g / cm 3 , at least one selected from the group consisting of the following (a) and (B) Fulfill. (A) The surface roughness Sa of the surface of the porous film as the outermost layer is 1.0 μm to 40 μm. (B) The surface of the base film that is the outermost layer is subjected to a mold release treatment. [Selection] Figure 1 |
