PURPOSE: To obtain a specific fibrous sheet having a bright color by combining color development due to not only the light interference but also a color tone different from that by the light interference and not only a bright light interference part but also a conspicuous part of a color and a pattern other than the light interference part.
CONSTITUTION: This fibrous sheet is characterized by having at least one surface of a substrate fibrous sheet provided with a metallic thin-film layer having 0.02-0.2μm thickness and an organic three-dimensionally cross-linked thin-film layer having 1.35-2.00 refractive index and 0.05-1μm thickness on the outside of the metallic thin-film layer and further at least the first color developed part having a reflectance of light within the range of 20-50% within a visible light region and the second color developed part having a reflectance different from that of the first color developed part.
