To provide a decorative sheet preferable for a wall and ceiling of a bathroom or the like at low costs, where designing characteristics, and resistance to hot water and alkalis are improved, by sequentially laminating a printed sheet layer composed of thermoplastic resin layers having an adhesive layer and a pattern printed layer and a surface protective layer on the top face of an inorganic base.

A printed sheet layer 5, where a pattern printed layer 7 composed of a solid ink layer 7a and a pattern ink layer 7b are provided on the upper side of thermoplastic resin film 6, is laminated on a sealer layer 3 provided on the side of an inorganic base 2, and a surface protective layer 8 composed of hardening resin coating is laminated thereon. For the inorganic base 2 used for an inorganic decorative sheet 1, a calcium silicate sheet, an asbestos slate, a lightweight foamed concrete plate, a plaster board, a pulp cement board, or the like can be named. The sealer layer 3 is provided for preventing eluting of alkali component from the inorganic base 2, where polyisocyanate resin or the like is used.
