PROBLEM TO BE SOLVED: To provide high heat efficiency by improving heat transfer efficiency between combustion gas and a cooking vessel. SOLUTION: A table cookstove 1 of this embodiment passes the combustion gas while colliding with a trivet claw 22 by flowing in a combustion gas passage partitioned in a series of spiral shape from a combustion gas inlet 33. When colliding with this trivet claw 22, the combustion gas changes a flow in the upward direction from the horizontal direction, and is sent outside in a series of spiral combustion gas passage while repeating a collision with a bottom surface of the cooking vessel P. and is exhausted outside from an exhaust gas outlet 34. The combustion gas causes a turbulent flow in the partitioned combustion gas passage, and a heat transfer boundary film is not formed on the bottom surface of the cooking vessel P, and the heat transfer efficiency between the bottom surface of the cooking vessel P and the combustion gas can be improved.
