PROBLEM TO BE SOLVED: To provide a method for easily and surely forming an inorganic foamed molding or a coating film, which contains many bubbles independent of each other and having uniform particle size, and to provide an inorganic composition suitable as a material therefor. SOLUTION: This inorganic composition contains a binder composed of an aq. solution of an alkali metal silicate and egg shell powder, which is a finely crushed material of the egg shell. The inorganic foamed molding is formed by using the inorganic composition as the material and carrying out a pre- molding forming process and a foaming and molding process in this order. In the pre-molding forming process, the inorganic composition is shaped into a prescribed shape and dried and solidified to form the pre-molding. In the succeeding foaming and molding process, the pre-molding is heated to be foamed to form the inorganic foamed molding.
