PROBLEM TO BE SOLVED: To provide an electrode temperature measurement method for improving accuracy of measuring a temperature of an electrode, and an electrode temperature measurement apparatus. ! SOLUTION: An electrode temperature measurement method for measuring a temperature of an electrode of a secondary battery by use of a radiation thermometer, in an atmosphere including water vapor evaporated from the electrode includes: measuring a temperature of an electrode 800 by use of a radiation thermometer 101, in an atmosphere including water vapor; measuring non-contact temperature of a blackbody plate 103, on the basis of radiation intensity of infrared rays emitted from the blackbody plate 103, in an atmosphere including water vapor; measuring contact temperature of the black body plate 103, by use of a thermocouple 104; calculating a correction value by use of the non-contact temperature and the contact temperature of the blackbody plate; and corrects a temperature of the electrode 800 measured by the |
