An austenite heat-resistant spheroidal graphite cast iron is disclosed which has a chemical composition including, in weight percent, 1-4.5% of Mo and 0.001-0.5% of Sn and/or Sb (2Sn + Sb). The austenite heat-resistant spheroidal graphite cast iron preferably has a chemical composition including, in weight percent, 1-3.5% of C, 1-6.5% of Si, not more than 3% of Cr, 10-40% of Ni, 1-4.5% of Mo, 0.001-0.5% of Sn and/or Sb (2Sn + Sb), and not more than 0. 1% of a graphite-spheroidizing element.
