<p>PROBLEM TO BE SOLVED: To provide a burner head capable of excellently forming flame and capable of thinning a body part.SOLUTION: A burner head 1 includes: a body part 2 that has an internal flow passage S in which combustion gas can circulate in a longitudinal direction; a plurality of flame holes 3 that is formed in the longitudinal direction of the body part 2, and can combust the combustion gas of the internal flow passage S; and a step part 4 that communicates the internal flow passage S of the body part 2 and the flame hole 3 while reducing its diameter toward the flame hole 3, and can jet the combustion gas of the internal flow passage S at the flame hole 3. The step part 4 is formed in the longitudinal direction of the body part 2 between flame holes 3 adjacent to each other.</p> |
