This paper concerns the errors involved in measuring surface temperature by sticking a thermocouple on the surface of building materials or building walls. The main causes of the errors are as follows : (1) the radiation character of sticking materials; (2) the heat conductivity of sticking materials; (3) the heat conductivity of a thermocouple. The results of our experiments show i) that it is desirable to make the width of sticking materials as short as possible because the sticking materials disturb the distribution of surface temperature, ii) that when the sticking length of a thermocouple is 100 to 150 times the diameter of the thermocouple, the measurement value is almost constant, and iii) that the heat character of measurement objects, that of sticking materials, wind, and radiation have a considerable effect on the measurement temperature. Thus we have obtained a better measuring method of reducing the errors.
