PURPOSE: An electric cooker is provided to prevent the formation of water drops inside a lid occurring due to temperature difference of the lid and a body by heating the lid during a boiling process. CONSTITUTION: One ends of a lid boiling heater(12), a lid warmth keeping heater(13) and a lid fermentation heater(14) are connected to the plus terminal of a main power source terminal(2). The other end of the main power source terminal is connected to the minus terminals of a body boiling heater terminal(3), a body warmth keeping heater terminal(4) and a body fermentation heater terminal(5). When the main power source terminal supplies power to one of the body boiling heater terminal, the body warmth keeping heater terminal and the body fermentation heater terminal, power is supplied to a lid(11). Thus, the lid is heated even during a boiling process. Therefore, the formation of water drops on the inside of the lid is prevented.
