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, while having a clearance gap with at least the housing 22 in the heat source chamber 23.
