PROBLEM TO BE SOLVED: To provide a liquefied gas feeder capable of supplying a liquefied gas of gas phase at a prescribed pressure or more. SOLUTION: This feeder comprises a vessel 3 for storing the liquefied gas; a gas conduit 5 communicating with the gas phase part within the vessel 3; a pressure detecting means 15 for detecting the pressure of the liquefied gas of gas phase passing in the gas conduit 5; and a heating means 7 for heating the liquefied gas in the vessel 3 when the pressure detected by the pressure detecting means 15 is a set value or less. The heating means 7 has a heating part 35 including an oxidation catalyst. The heating part 35 is set on the outer surface of the vessel 3 to heat the liquefied gas in the vessel 3 by the combustion heat generated by catalytic combustion of fuel. According to such a structure, since the vessel 3 and the liquefied gas in the vessel 3 are heated by the catalytic combustion of the heating part 35 of the heating means 7, when the pressure of the liquefied gas of gas phase is the set value or less, to increase the evaporation quantity, the pressure of the liquefied gas of gas phase to be supplied can be raised, and the liquefied gas of gas phase can be supplied at a prescribed pressure or more.
