Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for simply and economically producing a casting having a slender hole as cast having extremely little deformation, such as bending, strain. SOLUTION: This method for producing the casting having the slender hole as cast, is the one, with which molten metal for casting is poured into a mold disposing a non-metallic inorganic fine tube or bar-like core, and cooled and successively, after releasing a flask, the above non-metallic inorganic fine tube or the bar-like core is removed. The non-metallic inorganic fine tube or the bar-like core has desirably 300-1600 deg.C softening point. The above non-metallic inorganic fine tube or the bar-like core is desirably a quartz fine tube core.
