PROBLEM TO BE SOLVED: To provide an inorganic molding which is capable of stacking a design constitution part without being damaged, and its stacking method. SOLUTION: Roofing materials 11a, 11b which are inorganic moldings comprise two design constitution parts 12 and a joining and locking part 13 on which other roofing materials are loaded in the execution. A groove 14 is formed between the two design constitution parts, and a rib 15 having a projection 16 is formed on the position opposite to the groove 14 on the surface opposite to the groove 14. Projecting parts 17a-17d are formed on the surface of the joining and locking part, and recessed parts 21a-21d are formed at the position opposite to the projecting parts 17a-17d are formed on the back side. When a plurality of roofing materials 11a, 11b are stacked, roofing materials 11a-11b opposite thereto are abutted on each other through recessed parts 21a-21d, the projecting parts 17a-17d, the projection 16 of the rib 15, and the groove 14 so that the design constitution parts are not abutted on the roofing materials 11a-11b opposite thereto.
