A decorative sheet comprises a transparent or translucent base sheet having a rear surface on which protrusion and recess patterns are formed and a bright set-solid print layer or bright pattern print layer formed on a side of the protrusion and recess patterns of the base sheet. Each of the protrusion and recess patterns is composed of parallel lines, continuous curved lines or a combination of the parallel lines and the curved lines each composed of protruded and recessed portions each in form of a groove having a width of 1 to 100 .mu.m. The base sheet has a front surface on which a transparent resin layer may be formed. The transparent resin layer is formed of a hardenable resin. The decorative sheet also comprises the base sheet having a rear surface on which protrusion and recess patterns are formed, grain patterns formed on a side of the protrusion and recess patterns of the base sheet, and a bright set-solid print layer formed on a rear side of the grain patterns. Each of the protrusion and recess patterns being composed of a parallel lines, continuous curved lines or a combination of the parallel lines and the curved lines each composed of protruded and recessed portions each in form of a groove having a width of 1 to 100 .mu.m.
