Abstract: Embodiments relate to a decorative sheet having a hairline design and including successively, from a front surface side thereof, (A) a layer of a transparent resin film and (B) a layer of an ink paint film containing high brightness pigment. A plurality of linear hairline grooves is provided on a surface of the transparent resin film on a side thereof facing (B) the layer of the ink paint film containing the high brightness pigment. The decorative sheet has a surface resistivity of 1×105Ω or more on a rear surface side thereof. When the decorative sheet is placed on a dirt comparison chart created by the NPB in an environment of an illuminance of 600 lux, and is illuminated from below the chart at an illuminance of 17000 lux, a figure having a size of 5 mm2 on the chart can be visually discriminated. When the decorative sheet is placed on a gray scale for soiling stipulated in JIS L0805:2005 in an environment of an illuminance of 500 lux, the color difference between color chips numbers 4 and 5 cannot be visually discriminated.
