To provide an electric pot reducing the power consumption in preserving the heat.

The side of an inner vessel 51 is formed with an approximately perpendicular wall part 36 in the lower part of the bottom of the inner vessel 51 and the wall part 36 is formed thinner than the inner vessel 51. Even on the way where the heat of liquid under heat preservation conducts from the bottom part of a single structure vessel 1 to the side of an outer vessel 52 exposed to the outside the vessel 1, the speed of heat conduction can be suppressed by the longitudinally approximately perpendicular wall part 36 formed by downward extending a hermetically closed space 53. This constitution can suppress the increase in the power consumption of the heater 2 in preserving the heat to the minimum and reduce the power consumption for the heat preservation.
