PROBLEM TO BE SOLVED: To provide a liquefied gas fuel supply device for an automobile for quickly supplying liquefied gas fuel to the automobile by using pressure gas. SOLUTION: The liquefied gas fuel supply device comprises a large container 1 for storing liquefied gas to be filled into an automobile fuel tank, a small container 2 using a liquid head in the large container 1 for introducing the liquefied gas, a pressure gas container 3 for storing propane gas for pressurizing the small container 2, a dispenser 6 for filling the liquefied gas fuel from the small container 2 into the automobile fuel tank, a three-way valve 4 having three ports to which a gas phase portion at the upper part in the large container 1, the upper part in the small container 2 and the pressure gas container 3 are connected, respectively, and a control valve for controlling the three-way valve 4. The control means controls the three-way valve 4 to pressurize the small container 2 with the propane gas in the pressure gas container 3 during filling operation of the dispenser 6 and to communicate the gas phase portions of the small container 2 and the large container 1 with each other during filling stop.
