A heat-treatment is performed for the purpose of improving mechanical characteristics such as creep strength. In the heat-treatment, the superalloy is solution-treated at a temperature of the primary crystallized point or more of the γ' phase from γ monophase region to obtain a structure close to a γ monophase, so that the γ' phase precipitated at casting is resolved to make the structure close to the γ monophase and elements segregated at casting is diffused to make the structure homogenous.
