PROBLEM TO BE SOLVED: To accurately measure a temperature of a plate to be measured by suppressing influence of an error due to a background temperature even in an environment where a steel plate is vibrated.SOLUTION: A temperature measuring apparatus 1 of a plate to be measured includes: a cavity body 11 formed like a cylindrical shape with a lid and arranged so that an aperture 14 is directed to a surface of the plate to be measured; a radiation thermometer 10 arranged on a bottom 16 of the cavity body 11 to measure a surface temperature of the plate to be measured in the cavity body 11; a flange part 12 arranged so as to be expanded to the outside of the aperture 14 along an aperture edge of the cavity body 11; and temperature adjustment means 13 for controlling a temperature of an outer peripheral part of the cavity body 11 by dividing the outer peripheral part into a plurality of zones in accordance with distances from the plate to be measured. |
