To provide an inorganic decorative plate having excellent warm water resistance and design property without decrease in adhesive properties by generating extremely small mildew even in the case of using it in a water section such as a bathroom or washstand, and a method for manufacturing plate for easily manufacturing the plate.

In the inorganic decorative plate 1 comprising a primer resin layer 3, a print pattern layer 4, and a surface protective layer 5 sequentially laminated on a surface of an inorganic base material 2, the layer 4 is formed of polyurethane resin ink, and the layer 5 is formed of ionizing radiation curable resin. And, a sealer layer 3a may be formed on an upper surface of the material 2, and vinyl chloride acetate resin may be contained in ink for forming the layer 4.
