The utility model relates to a PTC electric constant temperature container, relating to a heating device and a boiling water vessel. The existing PTC constant temperature container is inconvenient to use. The utility model adopts the PTC heating element to conduct electric conduction and heat conduction, and is connected with the lower part of the metal inner bottom part of the constant temperature container. The main body of the container is made of double wall stainless steel structure, metal inner lining structure or corrosion resisting metal inner bottom piece structure. The bottom of the container is provided with a central electrode holder and a pole boot for connecting the power supply, and a ring-shaped electrode holder and a pole boots. The upper surface of the power supply seat for the constant temperature container is provided with an annular bulge, the inner side of the ring is a first electrode, and the outer side is a second electrode, which is respectively communicated with the central electrode holder and the circular ring-shaped electrode seat. A switch, a fuse and a light-emitting diode indicating current are connected in series in the power supply line, and a light-emitting diode indicating the power supply to be connected is connected in parallel. The constant temperature container can be applied to a plurality of power supplies.
