PROBLEM TO BE SOLVED: To provide a burner for a cooking stove having a structure capable of obtaining a proper flame contact state to a flame detector, from low flame as minute fire power to strong flame as high fire power, and capable of improving flame detection accuracy by the flame detector.SOLUTION: A burner head 3 is provided with a flame detection recessed portion 24, formed into the shape recessed inward in a radial direction. A pair of recessed portion internal first flame holes 25 and a recessed portion internal second flame hole 26 positioned between both recessed portion internal first flame holes 25 in opposition to a flame sensing portion of the flame detector, and forming flame smaller than that by both recessed portion internal first flame holes 25, are disposed on a depth wall surface of the flame detection recessed portion. The recessed portion internal second flame hole 26 has an outlet positioned at a radial outer side in the burner head 3 with respect to outlets of both recessed portion internal first flame holes 25. Flame formation spacial portions 27 for allowing the flame from each recessed portion internal first flame hole 25, to be formed toward a direction separating from the recessed portion internal second flame hole 26, are disposed at both sides in a circumferential direction, of the burner head 3 inside of the flame detection recessed portion 24. |
