A cooking apparatus is provided. The cooking apparatus includes a cooking cavity, an upper space formed above the cooking cavity, lateral side spaces formed to at opposite lateral sides of the cooking cavity, a rear space formed behind the cooking cavity, and a lower space formed below the cooking cavity. A fan provided in the rear space generates a cooling flow that cools components housed in the rear space. A cooling flow path extends from the rear space and into the upper space and lateral side spaces. Flow from the upper space enters the door to cool the door and is exhausted through a lower portion of the door. Flow from the lateral side spaces, which includes an exhaust flow from the cooking cavity, is guided to the lower space and exhausted. In this manner, the cooking apparatus can be completely cooled and cooking odors and heat appropriately exhausted by the cooling fan positioned in the rear space.
