To provide a decorative sheet, in which harmful and corrosive hydrogen chloride gas or the like generated at time of combustion are not accompanied and volatilization of a plasticizer or the like becoming a cause of hypersensitivity for a chemical substance is not produced and lapping workability, overlay workability such as vacuum moldability, V-cut workability and antibacterial properties are excellent.

The antibacterial decorative sheet is a decorative sheet 6 not less than two-layer structures, in which an olefinic resin layer 1 is made to a base sheet and at least one layer selected from a primer layer 3 and an ink layer 4 is laminated on one side or both sides thereof. The olefinic resin layer 1 is a propylene base block copolymer consisting of both a propylene-α-olefin random copolymer component (A) having ≥90 wt.% content of propylene and a propylene-α-olefin random copolymer component (B) having 55-90 wt.% content of propylene and is constituted of a propylene base block copolymer (X) having specific limiting viscosity. The outermost layer 3 as the decorative sheet 6 is constituted of a layer, in which polylysine or polylysine salt is added as an antibacterial agent.
