The invention provides a metal vacuum heat insulation container. In a vacuum heat insulation container (1), a gap between an inner container and an outer container (7)is vacuumized for the gas exhaust, a sealing member used for sealing an exhaust hole to form a vacuum heat insulation layer (9), and an outer side of the sealing member (11) is provided with a protection plate (13). A coating layer (15) is disposed on an outer side surface of an outer cylinder part (5), a coating layer (16) is disposed on an outer side surface of an outer bottom plate part (6), and a coating layer (17) is disposed on an outer side surface of the protection plate. Small gaps A and B between a surface of a concave part (12) and a protection plate are filled with gap coating layers (18),(19). When the vacuum heat insulation container is washed by water, the gap coating layers (18),(19) can be used to stop the water from entering the concave part (12) or the sealing member, therefore the metal of the sealing member or the concave part (12) can be corroded, and the reduction of the heat insulation performance caused by the corrosion can be completely prevented.
