PROBLEM TO BE SOLVED: To provide a heating cooking device capable of efficiently cooling electronic components dispersedly arranged in a machine chamber arranged below a heating chamber. SOLUTION: The heating cooking device is provided with the heating chamber 7, and the electronic components 50 supplying microwaves to at least the heating chamber 7 are provided in the machine chamber 2 below the heating chamber 7. A radial fan 30 is arranged so as to rotate in parallel with a bottom face of the machine chamber 2. Cooling of the electronic components 50 can be efficiently carried out without much temperature rising by supplying air sucked in from an inlet 48 of a bottom face center neighborhood to the electronic components 50 to carry out cooling, and then exhausting the air from an outlet 44 provided on a wall surface of a machine chamber 2 outer circumference, and supplying air sucked in by the radial fan 30 to the electronic components 50 by a short air duct.
