Wherein the heat conducting panel 2 is used for transferring infrared heat energy released by the combustion of the combustor 12. In a preferred embodiment, the heat conducting panel 2 is a directional heat conducting panel 2, so that infrared rays are conducted and radiated in a direction radiating outward from the interval penetrating through the heat conducting panel 2, but not in an extending direction of the heat conducting panel 2 itself. Therefore, when the gas cooker is in use, the region of the heat conductive panel 2 above the burner 12 is the high temperature region 4, and the temperature of the other regions is not significantly increased.
