[Object] To provide a surface temperature measuring apparatus that is capable of accurately measuring a surface temperature of a temperature measurement target material such as a steel material (e.g., a wheel, a steel pipe, a steel sheet, or a rail) in a cooling process with water, and a method of measuring the same. [Solution] A surface temperature measuring apparatus 100 according to the present invention includes a radiation thermometer 1 configured to detect thermal radiation light emitted from a surface of a temperature measurement target material W in a cooling process with water, a housing 2 having an opening on a temperature measurement target material W side, the housing 2 storing, in an inside of the housing 2, at least a light receiving unit 11 of the radiation thermometer 1 among structural elements of the radiation thermometer 1, and an optical glass 3 that is fit and sealed in the inside of the housing 2 between the temperature measurement target material W and the light receiving unit 11 of the radiation thermometer 1, the optical glass 3 being configured to transmit the thermal radiation light. The optical glass 3 has, on the temperature measurement target material W side, an end surface adjacent to the surface of the temperature measurement target material W. |
