PROBLEM TO BE SOLVED: To provide a cooked rice temperature keeping device which suppresses the yellowing of the cooked rice and the decline of the physical properties of taste and keeps the rice delicious even when the rice is kept at a constant temperature. SOLUTION: This cooked rice temperature keeping device is provided with: an oxygen pump 15 provided with one or more of cells provided with a planar solid electrolyte, a pair of electrodes, a gasket supporting the solid electrolyte, a pair of separators and a pair of collecting plates; an inner pot 1 for housing the rice; an openable and closable lid 8; a heating means 5; a temperature detection means 4; a control means 6 for heating the rice to a prescribed temperature by using the heating means 5 on the basis of the detection value of the temperature detection means 4; a gas discharge pipe 16 for discharging oxygen inside the inner pot 1 to the atmosphere by using the oxygen pump 15; and a sealing valve 17. Since the oxygen pump 15 discharges the oxygen inside the inner pot 1, the yellowing of the rice and the decline of the physical properties of taste are suppressed and the delicious rice is provided even when the temperature of the rice is kept.
