SUBSTANCE: decorative panel or tile, whose face surface is formed by hardening at least of cement with a plasticizer, has projections and/or cavities of not more than 100 mum, high or deep that are positioned on the face surface by rows, preferably by rectilinear ones, or adjacent projections and/or cavities staggered in them; at least in one of the rows the projections and/or cavities are made, respectively, of different height or depth and/or with a different cross-section area in the plane of the face surface. At least part of the sections of cavities or space between the projections may be filled with a material differing in color and/or composition from the color and/or composition of the face surface, and the face surface may be formed on the backing or the carrying layer of concrete or wood, or polymeric material preferably with high heat-insulating properties. Besides, the projections and/or cavities may have a tapered and/or spherical, and/or prismatic, and/or pyramidal shape. EFFECT: enhanced artistic expressiveness of decorative panel or tile with guarantee of its high operating properties, such as durability, mechanical strength and ecological safety. 4 cl, 7 dwg
