PURPOSE: A producing method for a burner head is provided to reduce producing cost through commonly using a die for forging and casting to produce burner heads with and without an opened hole unit. CONSTITUTION: To produce a burner head(6), a die formed by an upper die and a lower die is used. After forging or casting a mold for the burner head, burr(6a) is eliminated. While eliminating the burr on the mold, an opened hole unit(63) is formed by punching or cutting to complete the burner head. Herein, thickness for a burner head portion(65) located on an upper side of an inner circumference unit of a burner body is reduced to conveniently punching the opened hole unit.
