PROBLEM TO BE SOLVED: To decrease the number of part items and lower the cost of a heating cooking device in which wind generated by a cooling fan is guided to a heating chamber from an inlet port on the ceiling part of the heating chamber. SOLUTION: A duct 24 for guiding the air generated by the cooling fan 16 which passes through a magnetron 13 from an air guide duct 18 to the front side of the upper surface of a ceiling plate 3e of an inner box 3 (the ceiling part of the heating chamber) is composed of the ceiling plate 3e, a protruding part 20 provided in the ceiling plate 3e and serving as the reflecting plate of a heater 19 and a heat shield plate disposed in the upper part of the ceiling plate 3e. Thus, an exclusive intake duct does not need to be separately provided, so that the number of parts can be reduced and the cost can be lowered, which is different from a case where an exclusive intake duct is provided on the upper surface of the ceiling part of the heating chamber.
