Disclosed is an electric rice cooker including an adiabatic vacuum device having an adiabatic function of repressing an outside loss of a heat generated by a hot plate at a minimum and a keeping warm function of continuously maintaining a heat warmly therein. In the electric rice cooker, an outer case has an inner case disposed therein. A cooking kettle disposed inside the inner case for containing water and rice to be cooked. An hot plate mounted adjacent an outside surface of the cooking kettle for heating the cooking kettle. A lid removably covers a top of said cooking kettle. An adiabatic vacuum member mounted between the outer case and the cooking kettle for preventing a heat from being emitting from the cooking kettle to an outside. The electric rice cooker can repress a loss of an internal heat in a cooking kettle at a minimum by means of an adiabatic vacuum member so that a thermal efficiency can increase, and can continuously maintain the internal heat warmly at a keeping warm process.
