The present invention provides a fuel supply device which can supply solid fuel without requiring power. This fuel supply device 1 comprises: fuel storage 12 which is disposed in a higher place than a combustion chamber 11 and can store at least a predetermined quantity of solid fuel 10; a fuel passage 13 which guides the solid fuel 10 stored in the fuel storage 12 to the combustion chamber 11; and a stopper 14 which adjusts the input amount and stops the input of the solid fuel 10 into the combustion chamber 11. The fuel passage 13 has a configuration whereby the solid fuel 10 can move to the combustion chamber 11 via the weight of the solid fuel itself, and the solid fuel 10 has a shape that allows the solid fuel to move by rolling along the fuel passage 13. The solid fuel 10 has a spherical or wheel-like form. The solid fuel 10 has a coating layer 13a for preventing moisture, promoting combustion, or applying aesthetics, or a moisture preventing material or a combustion promoting material is kneaded into the solid fuel 10. The solid fuel 10 has a hole which allows air to pass therethrough. The fuel passage 13 includes a curved or straight passage.
