<p>PROBLEM TO BE SOLVED: To provide a burner for cooking stove that has good firing performance by generating a firing spark at a proper place by a firing device and securely firing a fuel gas discharged from a flame hole for firing.SOLUTION: There is provided a burner for cooking stove such that a plurality of main flame holes 41 are provided at a peripheral edge of a burner cap 2, a flame hole 40 for firing and a firing device 27 which generates a firing spark nearby it are provided between some adjacent main flame holes 41, and an outer peripheral wall 30 on a radially outer side of a wall part surrounding a periphery of a space 3 for retention which reduces the discharge flow rate of a fuel gas from the flame hole 40 for firing is formed into a concave curved surface 26 which is concave radially inward. An outer surface Ws of a border wall with the main flame hole 40 of the wall part surrounding the periphery of the space 3 for retention and an intermediate surface "m" of an outer surface Wo of the outer peripheral wall on the radially outer side of the wall part surrounding the periphery of the space 3 for retention are formed into a curved surface R.</p> |
