<p>PROBLEM TO BE SOLVED: To provide a surface protection sheet having a substrate layer with a rough-surfaced outermost surface, which is sufficient to make a foreign substance inconspicuous even if enclosed between the surface protection sheet and an adherend, the surface protection sheet capable of exerting sufficient and appropriate adhesive strength either on a smooth-surfaced adherend or a rough-surfaced adherend.SOLUTION: A surface protection sheet includes a white-based substrate layer, a black-based substrate layer and an adhesive layer in this order. The white-based substrate layer is an outermost layer. Surface roughness Ra of an outermost surface of the white-based substrate layer is 0.30μm or more, surface waviness Wa of the outermost surface of the white-based substrate layer is 0.40μm-0.60μm, and surface glossiness at 60° gloss of the outermost surface of the white-based substrate layer is 65 or lower.</p> |
