PROBLEM TO BE SOLVED: To provide a gas cooking stove improving heat efficiency by guiding flame or combustion gas to a corner portion from a bottom face of a cooking vessel to a side face, and the side face of the cooking vessel. SOLUTION: A plurality of guide members 30 are provided on an outer circumference of a ring plate 21 of a grate 20, and the ring plate 21 is composed of a substantially sector tabular member 31, and a support plate 33 supporting the cooking vessel P. A spring 32 is attached between a lower face of the tabular member 31 and a top plate 12, and it energizes the guide member 30 in an upward inward direction. When the cooking vessel P is mounted on the grate 20, the guide member 30 supports the corner portion C of the cooking vessel P by the support plate 33, and the tabular member 31 is arranged in a state hugging the corner portion C. Consequently, the combustion gas passes through a space between the tabular member 31, and the bottom face B and the corner portion C of the cooking vessel P, it rises along the side face S of the cooking vessel P by upward bending of an outer circumference side of the tabular member 31, and the bottom face B, the corner portion C, and the side face S are heated.
