PROBLEM TO BE SOLVED: To provide an inorganic material body having low heat storability used for stabilizing infrared ray reflecting performance in a glaze layer on a tile surface and to provide a method for producing the same. SOLUTION: Since a heat absorption rate in the glaze layer changes according to existing amount of transition metal oxide of spinel type crystal structure, heat storability of the glaze layer, that is IR ray reflecting performance thereof, is controlled by controlling existing amount of transition metal oxide of the spinel type crystal structure.
