The object of this invention is to provide a built-in microwave oven, installed in kitchen furniture as an integral part of the furniture. In the microwave oven of this invention, a suction grille (10) and an exhaust grille (20) are provided on the front wall of the external casing, with a side air passage connecting the suction grille (10) to the exhaust grille (20). An exhaust fan (22) is provided in the side air passage at a front portion around the suction grille, while a partition wall (60) is longitudinally installed at a position in back of the exhaust fan (22). A PCB thereon, is installed within the rear passage defined in back of the partition wall (60). In an operation of the microwave e oven, the air discharged from the side air passage by the suction force of the exhaust fan (22) partially flows around the PCB support bracket (70) to cool the PCB prior to flowing through the side air passage to reach the exhaust grille (20).
