PROBLEM TO BE SOLVED: To provide a liquefied gas supply system, capable of accurately measuring the supply quantity of actually supplied liquefied gas. SOLUTION: A supply quantity computing part 150 reads from a pressure detector 130 a pressure detection value P11 in a fuel tank before supplying liquefied gas to a fuel tank 30 as pre-supply pressure, reads from the pressure detector a pressure detection value P12 after completion of the supply to the fuel tank as after-supply pressure, computes a movement amount of vapor flowing in a gas phase pressure equalization pipe passage 40 from the pre-supply pressure, the after-supply pressure, and a supply quantity of liquefied gas to the fuel tank computed based on a flow rate measured by a capacitance flowmeter 64, and computes an actual supply quantity of liquefied gas supplied to the fuel tank by subtracting the movement amount of vapor from the supply quantity measured by the capacitance flowmeter.
