Title: Burner

Abstract: The present invention provides a burner capable of recovering more reliably a flame going out at one flame port via the transfer of flames from other flame ports when the burner is turned down. The burner according to the present invention is formed of two metal plates 10, 20 having substantially wave-shaped ends and superposed with the wave phases shifted. The burner comprises plural flame ports 12, 22 vertically alternately disposed along the ends of the metal plates 10, 20, and plural gas channels 14, 24 for supplying gas to the flame ports 12, 22. The burner further has a first deformed portion 16 where one metal plate 10 is deformed toward the other metal plate 20 at the flame port portions of one of the upper and lower flame ports 12, 22. In the first deformed portion 16, the vertical distance between the upper flame port center 12x and the adjacent lower flame port center 22x is shorter than the vertical distance between the centers of the correspondingly adjacent upper gas channel 14 and lower gas channel 24.
