Abstract: [Problems] A flat burner elongated in the longitudinal direction has, at an upper end thereof, a main burner port (63) and a flame retention port (64) positioned at least on laterally one side of the main burner port (63). The flat burner uses hydrogen-containing fuel as a fuel. Flash back is prevented at the flame retention port in which the gas ejection speed becomes relatively small.
