On thermal bridge which occurs the three-dimensional heat flow, numerical analysis and experiment were carried out, and their temperatures were compared. The software TB3D/FDM was used in calculation of the temperature distribution. The experiment was carried out at the artificial meteorological rooms which have indoor and outside space, and test specimen was set on the parting wall. Surface heat transfer coefficients of the tested 3-dimentional heat-bridge wall were deduced from the results of obtained surface temperature by carefully experiment, and they were used in the simulation by TB3D/FDM. The experiment reproduced the indoor and outside space in two artificial meteorological rooms, and test specimen was installed in the parting wall. As the result, there was a large temperature differences at the inner surface near the part of steel were crossed, and they were larger than that of the other part of surface. The possibility of the problem of the 1-dimensional handling of the heat flow for the inner cavity air on walls used at TB3D/FDM was shown.
