ABSTRACT:
When a substrate coated with a coating solution which oxidizes at high temperatures is heat-treated, an oxygen concentration of a treatment atmosphere is lowered when the temperature is low. Next, the substrate is heat-treated in the treatment atmosphere of which the oxygen concentration is lowered. Sequentially, the treatment atmosphere is returned to that with the original oxygen concentration after the passage of a predetermined time after completing the heat treatment. Thereby, the substrate can be heat-treated, with the oxidization of the coating solution being controlled.
