An object of the present invention is to provide a combustion burner that is capable of efficiently performing heating of a raw material powder by improving the dispersibility of the raw material powder that is ejected from a raw material powder-ejecting port using a simple configuration, and a combustion burner in which raw material powder introduction pipes that introduce the raw material powder inside a raw material powder supply pathway are provided so that axes that extend from central axes of the raw material powder introduction pipes do not intersect a central axis of the burner main body, and so that angles θ that are formed by central axes of the raw material powder introduction pipes and an outer surface of a second circular member are larger than 0° and smaller than 90°.
