PROBLEM TO BE SOLVED: To provide a fuel burner in a simple structure, capable of increasing the contact pressure of abutment faces between components and preventing fuel leakage. SOLUTION: In the fuel burner 1, a nozzle base table 2, a back plate 3 abutting on the nozzle base plate 2 and a nozzle tip 4 abutting on the back plate 3 are arranged in the nozzle axial line direction sequentially, and the nozzle tip 4 is pressed on the nozzle base table 2 side by the shoulder part 14 of a cap 13 to fasten and fix the inner periphery of the cap 13 to the nozzle base table 2. The abutment faces 2a, 3b of the nozzle base table 2 and the back plate 3 and the abutment faces 3a, 4a of the back plate 3 and the nozzle tip 4 are tapered inclining on the nozzle tip side from the central side toward the outer peripheral side.
