An invention of a method for production of a heat-resistant container, in which a raised bottom portion is displaced inwardly by reduction in internal pressure, is disclosed. The method is characterized by forming a raised bottom portion 11 smaller in wall thickness than a surrounding wall portion 12a by first blow molding using a heat-treating blow mold; and pushing up the raised bottom portion 11 by a secondary bottom mold, in performing second blow molding using a final blow mold, to increase the wall thickness of the surrounding wall portion 12a (ground portion 12) relative to the raised bottom portion.
