PROBLEM TO BE SOLVED: To provide quartz burner device capable of securing a wide and uniform high temperature zone at a focal position of the flame by properly mixing an oxyhydrogen gas, uniformly performing the heating treatment onto a target material to be manufactured or worked, and improving the strength and working accuracy of a product. SOLUTION: This quartz burner device comprises a cylindrical outer pipe 10 receiving an oxygen gas and a hydrogen gas, and extended in the injecting direction of these gases, a plurality of nozzle pipes 12 of a small diameter mounted in the outer pipe, and a nozzle pipe outer injection part 14 as a spacial part outside of the nozzle pipe, for injecting the supplied hydrogen gas toward the focal position. A local peripheral injection part 18 having an auxiliary pipe 16 concentrically mounted on an outer periphery of a central nozzle pipe 121 in at least the outer pipe 10 is mounted for injecting the hydrogen gas toward the focal position along the central nozzle pipe between the central nozzle pipe 121 and the auxiliary pipe 16.
