PURPOSE: A cooling efficiency of an electromagnetic chamber is maximized, thereby improving reliability and reducing manufacturing cost. CONSTITUTION: An electromagnetic chamber cooling structure comprises an intake air grill(85) to introduce cooling air. A vent motor assembly(70) intakes the cooling air and intakes smoke and heat of a lower cooking device and discharges these to outside. A bottom plate(100) forms a lower face of the electromagnetic chamber and has a stepped upper face.
