<P>PROBLEM TO BE SOLVED: To provide a burner tip structure capable of securing a sufficient mixing distance in a mixing section flow channel in which an atomizing medium flows, without increasing a dimension of the shape of a burner tip body, and increasing the consumption of the atomizing medium such as steam. Ž<P>SOLUTION: In this two-fluid type burner tip structure in which fuel oil is atomized by the steam in the burner tip body 10 and charged into a furnace, the inside of a steam main flow channel 11 has a two stage structure having a downstream side end section inclined face 11a and a step section inclined face 11b, an outlet opening of the mixing section flow channel 12A formed in a state of communicated with the downstream side end section inclined surface 11a of the steam main flow channel 11, is composed of a narrow angle injection hole 15A, and an outlet opening of the mixing section flow channel 12B formed in a state of communicated with the step section inclined surface 11b is composed of a wide angle injection hole 15B.
