PROBLEM TO BE SOLVED: To supply primary combustion air into a cooking stove body via a gap between a bottom face and a top plate of a burner body, to prevent tilting of the burner body, and to improve productivity in a gas cooking stove provided with a burner 3 having a mixing tube 30 with a downstream end facing a burner opening 221 opened in the top plate 2 covering a top face of the cooking stove body 1, and the burner body 31 exposed on the top plate with a larger diameter than the burner opening, and composed such that an inflow cylinder part 32a protrudedly provided on a bottom face center part of the burner body is fit on the downstream end of the mixing tube to supply an air-fuel mixture from the mixing tube to the burner body. SOLUTION: Upward protrusion parts 225 preventing tilting of the burner body 31 by abutting on the bottom face of the burner body 31 are plurally provided with intervals in a circumferential direction on a rim part of the burner opening 221 of the top plate 2. The primary combustion air is introduced into the cooking stove body 1 via a ventilation part 227 composed of the intervals between the protrusion parts 225 and 225. COPYRIGHT: (C)2006,JPO&NCIPI
