Abstract: A microwave oven having a cooking chamber and a fan housing, both of which are isolated by a partition is provided. The microwave oven includes a heater housing depressed from the partition toward the fan housing and having at least one air discharge hole formed thereon. The air discharge hole communicates with the fan housing and a convection heater is housed in the heater housing. A fan is installed in the fan housing blowing air from the fan housing into the cooking chamber through the air discharge hole and the convection heater. With this configuration, loss of heat is reduced, thereby improving the efficiency of cooking and reducing the cost of production.
