PROBLEM TO BE SOLVED: To provide a liquefied gas feeder capable of feeding a liquefied gas in a gaseous phase at a pressure more than a desired pressure. SOLUTION: The liquefied gas feeder is provided with a container 3 wherein a liquefied gas is stored, a gas pipe line 5 communicating with a gaseous section 4 in the container 3, a pressure detecting means 13 detecting a pressure of the liquefied gas in the gaseous phase in the pipe line 5, a heating section 9 provided beneath the container 3, a heat medium pipe line 11 feeding a heat medium to the heating section 9 and a valve 15 provided in the pipe line 11 and allowing the heat medium to flow into the heating section 9 if a pressure detected by the detecting means 13 becomes less than a set value. With such a constitution taken, the heating section 9 into which the heat medium flows heats a bottom face of the container 3. A quantity of vaporization in the liquefied gas is increased in the container 3 heated, thereby leading to an increase in a pressure in the container 3, thus enabling to increase the pressure of the liquefied gas in the gaseous phase passing through the gas pipe line 5.
