PROBLEM TO BE SOLVED: To provide a heating cooker capable of preventing combustion flame from being discharged to the external from an exhaust duct by an exhaust fan even when combustion occurs in a heating chamber because of a user's wrong use and the like. SOLUTION: This heating cooker comprises a heating cooker body having a heating chamber 11 for heating a heated object, a blower 4 having an impeller 41 and a casing 42 rotatably receiving the impeller 41, and discharging the air in the heating chamber 11, and the exhaust duct 2 having an exhaust guide face 22 for guiding the air blown off by the blower 4 to the external of the heating cooker body. The casing 42 has a circular arcuate guide face 42a for guiding the airflow generated by rotation of the impeller 41 to the rotating direction of the impeller 41, and a supply opening 42b formed from a part of the circular arcuate guide face 42a to one side in the tangential direction of the circular arcuate guide face 42a, and the rotating direction of the impeller 41 is opposite to the opening direction of the supply opening to generate turbulence in the exhaust duct 2.
