The purpose of the present invention is to provide a decorative sheet which has excellent post-processing resistance and is suitable for use in flame-retardancy applications. A decorative sheet (1) according to an embodiment of the present invention is provided with a plurality of resin layers. At least one of the resin layers comprises a uniaxially stretched resin sheet (3) or a biaxially stretched resin sheet (3) comprising a thermoplastic resin composition in which inorganic pigment vesicles, in which an inorganic pigment is encapsulated in vesicles provided with a single-layered outer film, are added to a polyolefin resin. The value of the dichroic ratio R is such that R ≥ 0.3, the dichroic value R being calculated using formula (1) from the absorbance peak values for a wave number of 997(±5)cm-1 in the infrared absorption spectrum in the direction parallel to the direction of extrusion during film-forming and the infrared absorption spectrum in the direction perpendicular to the direction of extrusion during film-forming, obtained by polarization Fourier infrared spectroscopy on the uniaxially stretched resin sheet (3) and the biaxially stretched resin sheet (3).
