PROBLEM TO BE SOLVED: To improve the stability of a fixed state of a flame detector and an ignition electrode and to decrease the number of required parts in a structure of vertically fixing the bar-like flame detector and the ignition electrode to a stop plate 5 fixed to a burner body. SOLUTION: This stop plate 5 includes first and second bent plates 55, 56 bent from both end parts in the horizontal direction of a center erected plate 54 in the surface and reverse directions opposite to each other. Both ends in the longitudinal direction of a spring member 4 passing through a spring insert hole 540 opened in the central erected plate 54 from the surface to the reverse side are respectively removably engaged with first and second engagement parts 550, 561 provided on the first and second bent plates 55, 56, respectively, and the flame detector TC and the ignition electrode 1 are respectively nipped and held by each corner inner surface of a boundary between the first and second bent plates 55, 56 and the central erected plate 54 and the spring member 4.
