PROBLEM TO BE SOLVED: To provide an inorganic decorative sheet for building in which the blending amount of iron oxide can be reduced. SOLUTION: Disclosed is an inorganic decorative sheet for building obtained by molding an inorganic material essentially consisting of cement and subjecting the same to autoclave curing. The inorganic material includes iron oxide particles with the average particle diameter of 0.1-0.5μm subjected to consolidation treatment under the conditions where atmospheric temperature is 50-90°C and a linear load is 100-180 kg/cm as a coloring agent by 1.5-7 pts.mass to 100 pts.mass of the inorganic material. By using the ones subjected to consolidation treatment as the iron oxide particles, the iron oxide particles can be uniformly dispersed into the inorganic material, and coloring power by the iron oxide particles can be increased.
