The head-on quenching of premixed flames on the single wall surface has been analyzed based on thermal theory and as results, the flame temperature, nondimensional flame thickness and a Peclet number, P^Q_e, have been obtained at the time of quenching. Then, to confirm the adequacy of the analytical results, experiments using a combustion vessel were performed, and photographs were taken at the moment of head-on quenching of methane/air flames on a single wall surface using the Schlieren method, to measure the flame thickness at the time of quenching. As a result, the following were confirmed : regarding the nondimensional flame thickness at the time of quenching, although quantitative differences are observed between experimental values and theoretical values, it is always larger than 1 under all experimental conditions; P^Q_e obtained from the experiments agrees qualitatively with that determined by theoretical analysis.
