PURPOSE: A burner is provided to prevent fuel from leaking from a fuel tank by preventing a lift from passing through the fuel tank. CONSTITUTION: A burner comprises a fuel tank(10), a wick cylinder, a wick(30), a lift(40), an inner combustion cylinder(50), and an outer combustion cylinder(60). The fuel tank has an air passage and a cover plate(14). The wick cylinder is lifted up inside the fuel tank and comprises an inner pipe body, an outer pipe body, multiple connection pieces, and a lifting bar(24). The connection pieces connect the bottom ends of the inner and outer pipe bodies to each other. Both ends of the lifting bar are connected to the top ends of both sides of the inner pipe body, and the bottom of the lifting bar is exposed to the lower side. The bottom surface of the wick is supported to the connection pieces. The lift lifts up the wick cylinder. The lower periphery of a spreading plate(51) of the inner combustion cylinder is fixed by multiple support pieces, and the bottom surface of the spreading plate is fixed to multiple fixing pieces(52). The upper peripheral surface(63) of the outer combustion cylinder is curved outward from the top end of the lower peripheral surface(61).
