PROBLEM TO BE SOLVED: To suppress an increase in the radial dimension of an electrical pot as much as possible even when a heat insulating member is provided on the outer circumference of an inner container. SOLUTION: The electrical pot comprises: a bottom member 1; the bottomed cylinder-shaped inner container 16 which is disposed at the center part of the bottom member 1 and houses liquid inside; an exterior body 14 disposed at the outer edge part of the bottom member 1 and forming a space part between the exterior body 14 and the inner container 16; a cylindrical heat insulating member 17 which is formed by vacuumizing the space formed between an inner surface cylindrical panel 44 and an outer surface cylindrical panel 45 having reinforcing structure and which is disposed in the space part between the inner container 16 and the exterior body 14; and a shoulder member 15 which is disposed at the upper opening part of the exterior body 14 and supports the inner container 16. Then, on at least one of the bottom member 1 and the shoulder member 15, an abutting part 5 or 30 for preventing heat convection by being abutted on the heat insulating member 17 is formed.
