PROBLEM TO BE SOLVED: To provide a relatively inexpensive fuel supply device capable of continuously supplying fuel. SOLUTION: The fuel supply device includes: a main fuel tank 2; a fuel supply passage 4 interposed between the main fuel tank 2 and an engine 3; a main pressure-feed pump 9 supplying liquified fuel in the main fuel tank 2 to the engine 3, through the fuel supply passage 4; a sub-fuel tank 6: an inter-tank passage 7 interposed between the sub-fuel tank 6 and the main fuel tank 2; a sub-pressure feed pump 16 supplying liquefied fuel in the sub-fuel tank 6 into the main fuel tank 2 through the inter-tank passage 7; and a control means 13 controlling the main pressure-feed pump 9 and the sub-pressure feed pump 16. The control means 13 supplies the liquefied fuel in the main fuel tank 2 to the engine 3 by the main pressure-feed pump 9, and drives the sub-pressure feed pump 16 when the liquefied fuel in the main fuel tank 2 is reduced by a predetermined amount to supply the liquefied fuel in the sub-fuel tank 6 into the main fuel tank 2 by the sub-pressure feed pump 16.
