Abstract: A cooking appliance is proposed. A casing (100, 200) may have a cavity (S) therein, and of which a front surface may have an air inlet part (242) and an air outlet part (243) at different heights. A plurality of heat sources modules may be arranged at different surfaces of the casing (100,200). A this point, a cooling fan module (810, 850) may be arranged in a first electric chamber (ES1) provided behind the air inlet part (242), and transfer suctioned air into a second electric chamber (ES2) provided behind the air outlet part (243). Accordingly, the air suctioned by the cooling fan module (810, 850) may be discharged after circulating to through the first electric chamber (ES1) and the second electric chamber (ES2), and in this process, the plurality of heat sources may be cooled.
