摘要： Provided are a laminated film and a pressure-sensitive adhesive tape each of which is adjusted so as to be capable of achieving compatibility between low haze property excellent in transparency and such large surface roughness that foreign matter such as a fish eye is hardly observed without fluctuations in mechanical properties of the entire laminated film or pressure-sensitive adhesive tape. Also provided is such a pressure-sensitive adhesive tape as described below capable of protecting the uneven surface of a member having unevenness on its surface. The pressure-sensitive adhesive tape brings together sufficient pressure-sensitive adhesiveness for, and sufficient releasability from, the member. In addition, even upon deformation of the member protected with the pressure-sensitive adhesive tape by, for example, lamination or continuous winding, the uneven shape does not deform and a base material layer in the pressure-sensitive adhesive tape is not damaged, and further, the pressure-sensitive adhesive tape is adjusted so as to be capable of achieving compatibility between low haze property excellent in transparency and such large surface roughness that foreign matter such as a fish eye is hardly observed without fluctuations in mechanical properties of the entire pressure-sensitive adhesive tape. Also provided is such a pressure-sensitive adhesive tape as described below. When a prism sheet having multiple triangle pole-shaped prisms fixed on its surface is used as the above-mentioned member having unevenness on its surface, the pressure-sensitive adhesive tape functions as a surface protective film capable of effectively protecting a lens surface, and brings together sufficient pressure-sensitive adhesiveness for, and sufficient releasability from, the prism sheet. In addition, when the prism sheet protected with the pressure-sensitive adhesive tape is brought into a state such as a laminated state or a continuously wound state, the emergence of irregularity (indentation) in the external appearance of the prism sheet to which the pressure-sensitive adhesive tape is attached can be suppressed. A laminated film of the present invention is a laminated film including a base material layer, a roughness-expressing layer, and a fine unevenness-erasing layer in the stated order, in which: the base material layer contains a thermoplastic resin; the roughness-expressing layer contains at least one kind of a resin component (A) selected from polyethylenes, ethylene-vinyl acetate copolymers, propylene-based polymers, and olefin-based thermoplastic elastomers; the fine unevenness-erasing layer contains a thermoplastic resin (B); an arithmetic average surface roughness Ra on the surface on the side of the fine unevenness-erasing layer is 1.0 μm to 3.0 μm; and the haze value of the laminated film is 30% or less.
