Thus, when the electric pressure cooker 1 is operated, the pressure in the inner pot 300 increases to generate a downward pushing force, and the force applied to the inner pot 300 is transmitted to the outer pot 100 through the supporting member 210 under the support of the supporting member 210. Due to the supporting member 210 between the inner pot 300 and the outer pot 100, the outer bottom surface of the inner pot 300 and the inner bottom surface of the outer pot 100 can keep a gap when the electric pressure cooker 1 works, so that the inner pot 300 and the outer pot 100 are prevented from pressing the electromagnetic heating plate 410, the electromagnetic heating plate 410 is prevented from being damaged, and the reliability of the electromagnetic heating plate 410 is improved.
