PROBLEM TO BE SOLVED: To provide a writing sheet, which can exert sufficient writing performance and erasing performance even when a crayon type writing material is applied thereto. SOLUTION: The writing sheet includes a hardened layer of a hardening resin composition on one side of a resin-made base material sheet, and a writing surface (10) of the hardened layer has irregular structures (11, 12) formed by embossing so that recesses are continued. The irregular structures have an arithmetic average surface roughness of 0.5-5.0μm, based on a method regulated in JIS B0601, an average wavelength of 30-300μm and a skewness of roughness curvature of -2.0 to -0.01.
