PROBLEM TO BE SOLVED: To provide a liquefied gas supply apparatus that can prevent pressure in container from increasing more than necessary, when the pressure in the container reaches a predetermined pressure or more. SOLUTION: The liquefied gas supply apparatus comprises: the container 3; a liquefied gas heating means 11 for heating the container 3; a heat medium heating means 15 for heating the heat medium flowing in a flow passage disposed to the liquefied gas heating means 11; a heat medium conduit 17a for leading the heat medium from the heat medium heating means 15 to the liquefied gas heating means 11; a heat medium amount adjusting means 17c, 19 for adjusting an amount of the heat medium flowing from the heat medium heating means 15 to the liquefied gas heating means 11; a tubular body 55 of which both ends are closed to cover the portion where a gas conduit 7a communicating to a gas phase portion 5 is installed to be brought into close-contact with the heat medium conduit 17a; and a pressure detecting means 9 for detecting the pressure of the liquefied gas of the gas phase flowing into the container 3 or a gas conduit 7. A control portion 21 makes the heat medium amount adjusting means 17c, 19 reduce the amount of the heat medium flowing from the heat medium heating means 15 to the liquefied gas heating means 11 when the pressure detected by the pressure detecting means 9 is a predetermined pressure or more, and lowers a temperature of the heat medium heated by the heat medium heating means 15.
