Claim:
1. A combustion burner comprising: at least a burner main body that forms a flame and two or more raw material powder introduction pipes, wherein the burner main body has a plurality of pathways, which include a raw material powder supply pathway that supplies raw material powder and one or more pathways that are provided on an inner side of the raw material powder supply pathway, and which are formed by a plurality of circular members, which are disposed concentrically, a raw material powder-ejecting port that ejects the raw material powder that is supplied by the raw material powder supply pathway, and a plurality of ejecting ports that are positioned on an inner side of the raw material powder-ejecting port, the raw material powder supply pathway is formed by a first raw material powder supply pathway-partitioning circular member that partitions an outer side of the pathway, and a second raw material powder supply pathway-partitioning circular member that partitions an inner side of the pathway, and the two or more raw material powder introduction pipes are provided in the first raw material powder supply pathway-partitioning circular member, 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 that are formed by central axes of the raw material powder introduction pipes and an outer surface of the second raw material powder supply pathway-partitioning circular member are larger than 0° and smaller than 90°, and are disposed so as to be rotationally symmetrical to a central axis of the burner main body.
