Zusammenfassung:	PROBLEM TO BE SOLVED: To estimate a temperature of a high-temperature member with high accuracy, in a temperature estimation method and a life determination method of the high-temperature member.SOLUTION: A structure of a heat transfer tube is compared with a plurality of aging material structures having different deterioration degrees, and a value of a Larson-Miller parameter is evaluated based on the aging material structure corresponding to the structure of a heat transfer tube. The value of the Larson-Miller parameter is substituted into a Larson-Miller parameter relation to estimate a temperature of the heat transfer tube.
