Abstract
To provide a decorative sheet with a texture that closely resembles the surface texture of wood veneer and other materials used in building construction. [Solution] The decorative sheet 1 comprises a colored thermoplastic resin layer 2, a pattern layer 3, a transparent thermoplastic resin layer 4, and a surface protection layer 5 laminated sequentially on one side of the colored thermoplastic resin layer 2, and a gloss matte pattern portion 6 laminated on the other side of the colored thermoplastic resin layer 2, made of a predetermined material having higher light absorption properties for a predetermined wavelength than the colored thermoplastic resin layer 2, and positioned in synchronization with the pattern of the pattern layer 3. The surface protection layer 5 comprises, on its outermost surface, an uneven region Aa in which an uneven shape is formed at a position overlapping with the gloss matte pattern portion 6 in a plan view, grooves 51 formed at a position not synchronized with the pattern of the pattern layer 3, and an unformed region Ab in which the uneven shape and grooves 51 are not formed.
