The objective of this paper is to clarify the thermal combined effect of the KOTATSU and an electric hot carpet on the human body. A series of experiments were conducted under the following combined conditions: three air temperature levels (8℃, 11℃ and 14℃) and three infrared lamp levels ('off, 'low' and 'high') with electric hot carpet level of 'high'. The following results were obtained: 1) The increase in thermal sensation vote with increasing mean skin temperature is apparent, and the trend is quite similar to the previous studies. 2) The mean skin temperature under using the KOTATSU and an electric hot carpet was higher than that under using only KOTATSU. The subjects seating at the KOTATSU with an electric hot carpet reported warmer than the subjects seating at the KOTATSU without a hot carpet. 3) Using the KOTATSU with an electric hot carpet has equivalent effect of 13℃ operative temperature rise at air temperature of 10℃.
