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 plateshaving substantially wave-shaped ends and superposed with the wave phases shifted. The burner comprises plural flame portsvertically alternately disposed along the ends of the metal platesand plural gas channelsfor supplying gas to the flame portsThe burner further has a first deformed portionwhere one metal plateis deformed toward the other metal plateat the flame port portions of one of the upper and lower flame portsIn the first deformed portionthe vertical distance between the upper flame port centerand the adjacent lower flame port centeris shorter than the vertical distance between the centers of the correspondingly adjacent upper gas channeland lower gas channel
