摘要： The present invention provides a sheet, wherein the sheet has an excellent low-gloss feeling; even when oblique light is incident on a surface of the sheet, diffuse reflection of the light is suppressed, the surface is less likely to look white when viewed obliquely, and a design represented on the sheet can be visually recognized; and the sheet has excellent designability. In the sheet, a surface of the sheet has an arithmetic average roughness Ra (JIS B0633: 2001) of 0.7 μm or less, and the reflectance at a detection angle equal to a regular reflection angle ±5°, measured by a variable angle photometer when the surface is irradiated with incident light at an incident angle of 75°, is 50% or less of the reflectance at the regular reflection angle.

The present invention provides a decorative sheet comprising a base material sheet and at least a surface-protecting layer on the base material sheet,
(1) the base material sheet being a thermoplastic resin sheet,
(2) the surface-protecting layer having a surface free energy of 40 mJ/m2 or more,
(3) an arithmetic average roughness (Ra0.08) measured on the surface side of the surface-protecting layer at a cutoff value of 0.08 mm with an evaluation length of 0.4 mm by a measurement method in accordance with JIS B0601:2001 being 0.60 μm or less, and
(4) a specular glossiness on the surface-protecting layer side of the decorative sheet at an incident angle of 60° being 23 or less.-
