PURPOSE:To provide a cooking stove having a wide combustion range and high stability by installing pilot and main burners each of which has mixing tube and many flame holes on it and also independent gas flow path. CONSTITUTION:Fuel leaving route 34 flows into path 35 for pilot burner and flow path 36 for main burner separately via combustion adjusting holes 39, 40 for pilot burner and holes 41, 42 for main burner and finally gas is supplied to burner mixing tube 16 for pilot and tube 15 for main via path 35, and nozzle 26 for pilot and path 36 and nozzle 27 for main. After flame 45 is formed by ignition to pilot flame holes 23, thermocouple 9 is heated up and safety valve 29 which is forced to open by a hand-operated knob becomes self-holding by electric current from thermocouple, combustion is continued without holding main knob 7 by hand. On the other hand, pre-mixed fuel which is supplied from main burner mixing tube forms main flames 44 and combustion is continued.
