ABSTRACT:
A cooking apparatus to improve heating efficiency and to quickly cook food. The cooking apparatus includes a heater provided at a tray receiving food to be cooked and having a pair of terminals to supply power to the heater, and a plurality of sockets provided at a rear wall of a cooking cavity. When the tray is placed on a pair of support rails of the cooking cavity and the terminals of the heater are inserted into one of the sockets, the tray is directly heated by the heater to cook the food. The heater includes a conductive film coated on a lower surface of the tray, and first and second electrodes connected to the conductive film to be opposed to each other and connected to the terminals. The conductive film and the tray are heated by current flowing through the conductive film between the first and second electrodes.
