In order to mainly increase the degree of freedom in forming the central flame port, the deep ends of the other protrusions 3 except for the protrusions 2 on both sides of the protrusion 1 facing the recess as shown in FIG. It is set outside. For this reason, when the burner cap 30 is mounted on the burner body in a slightly floating state due to solid matter adhering to the joint surface between the burner cap 30 and the burner body, the mixed gas from the gap is indicated by arrow K. Has a drawback that the air flows easily, the air-fuel ratio in the recess becomes too much gas, and ignition becomes difficult. The object of the present invention is, even when the burner cap is mounted on the burner body in a slightly floating state,
This is to provide a stove burner that can secure good direct ignition.
