A burner arranged such that flames turned off at one flame port when the burner is turned down can be recovered more reliably by the transfer of flames from the other flame port. This burner is formed of two metal sheets (10, 20) having substantially wave-shaped ends by superposing the metal sheets while shifting the wave phase. Further, the burner has a plurality of flame ports (12, 22) vertically alternately disposed along the ends of the metal sheet (10, 20), and a plurality of gas passageways (14, 24) for feeding gas to the flame ports (12, 22). Further, the burner has a first deformed section (16) where one metal sheet (10) is deformed toward the other metal sheet (20), at the flame port portion of one of the upper and lower flame ports (12, 22). The vertical distance between the adjacent upper and lower flame port centers (12x, 22x) of the first deformed section (16) is shorter than the vertical distance between the centers of the upper and lower gas passageways (14, 24) correspondingly adjacent to each other.
