A microwave oven includes a tray holding unit which stably holds both a cooking tray and a tray guide at their original positions regardless of vibration and impact applied to the cooking tray and/or tray guide. The tray holding unit includes a base part, and elastic blade parts which are formed on both sides of a lower surface of the base part and extend downward from the lower surface while being inclined outward at an angle of inclination. A stop rail is horizontally formed along an inner surface of left and right sidewalls of a cooking cavity of the microwave oven, so as to stop top edges of the base part and allows the blade parts to press down on the cooking tray. Accordingly, the cooking tray and the tray guide are stably held down by the tray holding unit.
