PROBLEM TO BE SOLVED: To provide a foaming preparation capable of being produced without causing agglomeration, nor with the aid of a binder, having such size distribution that primary particles are distributed in a narrow range, scarcely requiring energy for being pulverized, and therefore friendly to the environment when produced, and further scarcely forming dust, and to provide a method for producing the foaming preparation. SOLUTION: This foaming preparation contains (a) at least one kind of organic and/or inorganic foaming agent and, if necessary, (b) a surfactant compound, wherein the foaming preparation has a water content of less than 3 mass % based on the foaming preparation and an average primary particle size of 20-5000μm.
