摘要： A resin sheet of the present invention is a checker glass-like resin sheet made of a transparent thermoplastic resin, and includes a plurality of sectional arch-shaped elongated protrusions extending in one direction are regularly arranged in rows on, one surface of the resin sheet; and a plurality of sectional arch-shaped elongated protrusions extending in a direction perpendicular to the protrusions arranged on the one surface are regularly arranged in rows, on another surface of the resin sheet, in which an arithmetic average waviness (Wa) at a vertex of the protrusion in a direction in which the protrusion extends is 20 μm or less on both surfaces of the resin sheet. Accordingly, there is provided a resin sheet that can be used as an alternative to checker glass and has a certain degree of visibility from a short distance while having a shielding property from a long distance.
