To provide an inorganic decorative board excellent in designability, in which the surface is painted without losing the designability of the sharp concavo-convex pattern applied on the surface, and to provide a method for producing the same and a method for constructing the same.SOLUTION: Provided is an inorganic decorative board 50 comprising a surface layer 11 as an inorganic layer containing mineral fiber, inorganic powdery material and binder as main component, and having a paint film 30 formed by inkjet painting on the surface 1 of a heat-compressed product having concavo-convex pattern formed on the surface 1 to be a decorative surface by embossing die 20, and in which the paint film 30 formed on the surface 1 on which a concavo-convex pattern having a plurality of grooves 3 to be concave portions is formed, is formed such that the in-groove paint film 30a formed on the inner surface of the plurality of grooves 3 has a deeper color than the out-of-groove paint film 30b formed in the other portions than the grooves 3.SELECTED DRAWING: Figure 3 【課題】表面に施されたシャープな凹凸模様の意匠性を損なうことなく表面を塗装した意匠性に優れた無機質化粧板、その製造方法及び施工方法を提供する。【解決手段】表層１１が鉱物質繊維と無機質紛状体と結合剤とを主成分として含む無機質層に構成され、エンボス型２０によって化粧面となる表面１に凹凸模様が形成された加熱圧縮形成物の上記表面１にインクジェット塗装によって塗膜３０が形成されてなる無機質化粧板５０において、凹部となる複数の溝３を有する凹凸模様が形成された表面１に形成された塗膜３０を、複数の溝３の内面に形成される溝内塗膜３０ａが、該溝３以外の部分に形成される溝外塗膜３０ｂよりも濃色になるように形成する。【選択図】図３
