Abstract
The present invention addresses the problem of providing a surface-protective film which is excellent in terms of antiglare property, scratch resistance, and oil resistance. Provided as a means for solving the problem is a surface-protective film which comprises a protective layer constituted of a polyurethane, both surfaces of the protective layer being flat, and a hardcoat layer formed on one of the surfaces of the protective layer, wherein the hardcoat layer has an arithmetic average roughness Ra of equal to or greater than 0.1 and equal to or less than 0.8 μm.
