PURPOSE: A cavity ventilation structure is provided to achieve improved use convenience by forming a smooth air flow in the cavity of a microwave oven. CONSTITUTION: A ventilation structure comprises a pair of inlet units(52,54) arranged at both sides of the front portion of a cavity top surface(50) in such a manner that the inlet units are communicated to a cavity of a microwave oven; and a pair of ventilation units(56,58) arranged at both sides of the rear portion of the cavity top surface in such a manner that the ventilation units are positioned in the vicinity of ventilation fans(72,74). An ambient air flows into the cavity through the inlet units by the operation of the ventilation fans, and the air existing in the cavity is ventilated through the outlet units and a ventilation motor assembly(70).
