PURPOSE:To form a uniform flame over an entire surface of a combustion face by a method wherein a circular burner head is constructed in such a way that there is no connection part at its circumference of the combustion surface. CONSTITUTION:A burner head 6 is made in an annular form by pressing a shape sheet composed of a metallic net, and a stepped flange 6a is arranged at an end part where a head pressing plate 4 is fixed. Fuel fed from an injection port 1 may suck the surrounding air, enter a throat and is mixed with air and then goes into the burner head 6. Since there is no connection at the burner head 6, loss of pressure is made uniform and mixture is uniformly injected to form a flame 8.
