PURPOSE:To perform a stabilized combustion by completely vaporizing even plenty of liquefied fuel by forming the nozzle member of the combustion device of a liquefied gas in the hollow structure having a closed space and by leading the liquefied fuel to a gas blowing out part via this closed space. CONSTITUTION:The liquefied fuel inside the liquefied gas tank 3 of a butane, etc. is sucked by a suction pipe 5 and led into the closed space 12 inside a nozzle member 11 via a gas feeding pipe 13. It is further led to the base end inner part of a gas outlet port member 9 via a leadout pipe 14 and gas return pipe 15 and after removing the foreign matter in the gas by a filter 16 it is jetted into the mixed gas forming member 10 from a nozzle hole 17a. The outside air is taken into the mixed gas forming member 10 through inlet ports 19, 20 by the ejecting action at the gas jetting time from the nozzle hole 17a, the mixed gas of the liquefied gas and air is formed therein and jetted into the nozzle member 11, the mixed gas is ignited by the spark of an ignition plug 23 and a flame is jetted from the nozzle member 11.
