Simultaneously with the start of combustion at 3, the heat radiating surface 4 is heated to make it red heat, and at the same time, the heat radiating surface 4 generates radiant heat to start cooking the cooked object 8. At this time, the time required for cooking the cooking object 8 depends on the radiant heat emitted from the heat radiating surface 4 and requires a long time. Generally, the radiation efficiency of the gas infrared burner 2 having the heat radiation surface 4 mainly composed of SiO 2 is about 30.
It is said to be about%, and this value was the limit. Therefore, in order to increase the amount of radiant heat, a means of increasing the surface area by making the surface of the heat radiating surface 4 uneven is used.
However, it has not been possible to respond to the market demand for shortening the cooking time of the cooked food 8.

る。In the above configuration, when gas is supplied to the gas infrared burner 2 and burned, the heat radiation surface 4 of the ceramic plate 5
The heat-resistant high radiation layer 10 provided on the surfaces of the outer peripheral flame hole group 14 and the inner flame hole group 15 is heated and red-heated. The heat radiation surface 4 is a heat-resistant high radiation material having an emissivity higher than that of the base material forming the heat radiation surface 4.
Since 10 is provided on the surface, more radiant heat is generated and the cooking target 8 is heated and cooked in a short time. This effect is most effectively obtained when the heat resistant high radiation layer 10 is provided in both the flame hole groups 14 and 15 and the flameless hole portion 16. Also, since the atmosphere temperature distribution in the cooking chamber 7 of the baking cooker 1 has heat escape from the surroundings, the central part of the cooking chamber 7 has the highest temperature and the surroundings has the lowest temperature. Then, since the flame hole groups 14 and 15 are arranged and the flameless hole portion 16 is provided, there is an effect that a uniform charring performance of the food 8 can be obtained.
