PROBLEM TO BE SOLVED: To provide an exothermic material for casting and an exothermic formed article for casting with which the burnt residue of easily oxidizing metal is reduced in order to eliminate a harmful influence developing pin hole in a cast product. SOLUTION: This exothermic material includs the easily oxidizing metal and an oxidizer containing >=10 wt.% grains of <=50μm grain diameter. Further, the exothermic material includs an aggregate and binder together with the included materials. Furthermore, the exothermic material includs a combustion improver together with the included materials. Then, the exothermic formed article for casting is the one forming the exothermic material.
