A cooker is provided to prevent a knob from becoming heavy by forming at least one opening in the knob although volume of the knob is increased. A cooker comprises a cooking space(100) in which a cooking operation is performed using microwave. A door(200) opens and closes the cooking space. A knob(210) is provided at the upper portion of the door to be used for opening and closing the door. The door includes a front plate(220) formed at the front surface of the door, an opening(291) and an air path. The opening is formed in the rear upper portion of the door such that air flowing in the cooking space is flowed into the door. The air path allows the air inlet through the opening to flow from the upper portion of the door to the lower portion of the door. The knob has a through hole and a communication hole that communicates with the through hole.
