The invention provides a stove burner provided with main burner part and a subsidiary burner part, wherein the main burner part is provided with a plurality of open main flame ports (4m) on the periphery of a burner head (3); the subsidiary burner part is provided with a plurality of open main flame ports (4s) on the periphery of the burner head and on a lower side of the main flame ports. The stove burner can freely switch between a mode of only supplying gas to the subsidiary burner part so as to burn a subsidiary burner only, and a mode of only supplying gas to the main burner part so as to burn a subsidiary burner only. The subsidiary burner part is formed by a natural gas supply type burner and can absorb primary air from a flow inlet (5sa) at an upstream end of a subsidiary burner hybrid tube (5s); the main burner part is formed by a forced air supply type burner capable of forcedly supplying primary air from an air supply fan (8) connected to a main burner mixing tube (5m). Accordingly, even though an external diameter of a burner is reduced, poor combustion caused by lack of primary air in the main burner part can be avoided. |
