PURPOSE:To enable extremely accurate detection of the actual temperature environment in a room, by specifying the dimensions and the supply heat value of a heat generating body in the optimum range to make a thermal detection element much more approach actual feeling of a human body. CONSTITUTION:In a thermal detection element which is provided with a heat generating body 1 having an electric heater 4 and a temperature measuring device 7 for measuring the surface temperature Tg of the heat generating body 1 in a hollow spherical shell 3 to supply a specified hat value to the heat generating body 1 while adapted to detect the warm temperature state in a room environment based on the surface temperature Tg thereof, the diameter D of the spherical shell 3 of the heat generating body 1 is set at D=100-140mm. Moreover, the supply heat value M to the heat generating body 1 is set at M=76-93W/m2. The diameter D of the heat generating body 1 and the supply heat value M are set being allowed for the moisture based radiation of the human body. Thus, the thermal balance of the element creates a very close correlation with the thermal balance of the human body and a single detection element is enabled to detect the temperature state which can make the human body comfortable at a high accuracy.
