PROBLEM TO BE SOLVED: To reduce temperature of a lamp illuminating a second heating cooking apparatus provided downward in which produced gas is prevented from entering the neighbourhood of the lamp to prevent a lamp surface from being contaminated and insulation resistance of a charging section from being reduced. SOLUTION: A space in which there are disposed a product gas intake port 6 and a lamp 3 is divided with a shielding plate 16, and a paint other than a black colored one is applied on a back surface of a bottom of a heating chamber 7 or a surface of the same on the side of the lamp 3. Accordingly, even when sealing properties of the lamp are not increased, product gas is prevented from invading, and hence a lamp 3 surface is prevented from being contaminated and insulation resistance of a charging section is prevented from being reduced. Thus, temperature of line lamp 3 is reduced with a simplified construction and light from the lamp 3 is effectively reflected to illuminate a second heating cooking apparatus 2 located below.
