Provided is a vacuum heat-insulating container including an outer cylinder having a bottom and an inner cylinder having a bottom and disposed inside the outer cylinder, with a vacuum space formed between the outer cylinder and the inner cylinder. The inner cylinder and the outer cylinder are disposed such that an opening plane of the inner cylinder is located outward of an opening plane of the outer cylinder. The outer cylinder has a first annular wall. The inner cylinder has a second annular wall. The vacuum heat-insulating container further includes an annular sealing member that is made of an elastic body having a lower coefficient of heat transfer than the outer cylinder and the inner cylinder, and that is squeezed between the first annular wall and the second annular wall so as to seal the vacuum space.
