SOLUTION: A negative power source grounded at the positive.side thereof is used for a power source 16. A negative electrode 17 and a positive electrode 18 are constituted of a metal, and arranged substantially concentric with a burner 12 in such a way as to sandwich gas flame 21. In addition, the positive and negative electrodes 18 and 17 are constituted of, for example, rings having diameters of 110 mm and 50 mm, respectively. When a user pushes an ignition button or the like provided at the front of a housing 11, the burner 12 belches out gas flame 21 to heat a pan 15. At that time, the electric source 16 operates to apply an electric voltage of about -10 kV to the negative electrode 17. As a result, a direct electric field is applied between the negative and positive electrodes 17 and 18. The gas flame 21 containing plus ions is drawn toward the negative electrode 17.
