By using a premixed laminar burner, the effect of humidity (H_2O) on burning velocity (S_L) was investigated. The following was made clear ; (1) As the H_2O, CO_2 and Ar in mixture is increased, S_L decreases in proportion to the quantity of those dilution gases. (2) The heat reaction theory says that mean thermal conductivity (λ_m), specific heat (C_<pm>) of mixture and adiabatic flame temperature (T_b) affect S_L. As a result of theoretical analysis, the effect of λ_m and C_<pm> on S_L is less than 1/25 of the effect of T_b, so the effect of λ_m and C_<pm> can be ignored. (3) From experimental results, it was confirmed that ln (S_L) is proportional to (1/T_b), that is, the effect of H_2O on S_L is mainly caused by changes of T_b. This conclusion was verified by the fact that increases of H_2O, CO_2 and Ar decrease the intensity of radiation typical C_2, CH and OH in the same manner.
