Field survey on indoor air quality was conducted in winter season, in a classroom of an elementary school in Kagoshima city. The windows has been often closed because of avoiding the cold outdoor air in winter season. Therefore CO_2 concentrations during pupils' staying in the classroom were over 1500 ppm at the end of the lesson. Since the windows of the corridor facing outside had been open, CO_2 concentrations were close to the outodoor CO_2 concentrations. VOC of 2-hydroxy propanoic acid might be emitted from pupils since it detected when they stayed in the classroom. It was found that the ventilation during the break could play and important role in CO_2 concentrations during the next lesson. The CO_2 emission rate from one third grader pupil was calculated as 0.011m^3/h.
