PROBLEM TO BE SOLVED: To increase speeds in preheating of a heating chamber and heating cooking, by efficiently heating a heated object while suppressing radiation loss due to heating of only a wall surface by hot air. SOLUTION: In this heating device including the heating chamber 13 in which the heated object 12 is placed, a partitioning wall having a suction opening 26 and at least two supply openings 29, 30, and configuring the wall surfaces 17, 18 of the heating chamber 13, and a heat source chamber 23 disposed outside of the heating chamber, having a housing 22 forming a space with the partitioning wall 19, and supplying hot air to the heating chamber 13 from the supply openings 29, 30 by an air distribution fan 25 and a heating means 24 disposed in the space, the hot air from the supply openings 29, 30 on positions provided with roughly L-shaped partitioning plates 32, 33 can be concentrated in the central direction in the heating chamber 13 in preheating, while having a clearance gap with at least the housing 22 in the heat source chamber 23, and the supplied warm air can be unified by closing most of the supply openings 29, 30 by inserting a cooking pan 21 into the heating chamber 13 in cooking.
