PURPOSE: A microwave oven is provided to prevent input of condensed water to a PCB(Printed Circuit Board) on a front surface of a driving cavity to be stored on a condensed water receiver on an upper end of a cabinet. CONSTITUTION: An air ventilating hole(6a) is formed on a separate wall(6) separating a cooking cavity from a driving cavity(7) for discharging air to outside through the cooking cavity. Therefore, overheat of the driving cavity is prevented. The driving cavity contains a PCB(8) having a circuit controlling function keys, a ventilator(9) preventing increase of temperature, a magnetron(10) generating microwave, a high voltage transformer(11), and a high voltage condenser(12). Moisture generated in the cooking cavity is inputted to the driving cavity through the air ventilating hole on the separate wall. Then, the moisture is converted into condensed water by attaching to an external panel covering an upper surface of the driving cavity. A condensed water receiver(13) is integrally formed with a cabinet at an upper side to prevent the water from being inputted to the PCB.
