<P>PROBLEM TO BE SOLVED: To provide high silicon spheroidal graphite cast iron having excellent heat resistance, oxidation resistance and castability, and suitably usable for automobile engine parts such as turbocharger housing, exhaust manifolds and exhaust system parts, and to provide a method for producing the same. Ž<P>SOLUTION: The spheroidal graphite cast iron includes oxygen (O) and sulfur (S), each by mass, ≤25 ppm of O and ≤0.015% S, and further includes 2.5 to 3.8% C, 4.1 to 8.0% Si, 0.2 to 0.7% Mn, 0.008 to 0.029% Mg and 0.02 to 0.15% P, and the balance iron (Fe) with inevitable impurities.
