[Object] To provide a thermal insulation container with which the heat/cold insulation effect is kept for longer time without increasing the size and weight of the thermal insulation container. [Solving Means] The thermal insulation container includes an inner container, an outer container, and an overlap region. The inner container includes a first bottom portion, a first side wall portion that extends in a first direction from the first bottom portion and forms a first open end portion, and a first vacuum layer continuously formed inside the first bottom portion and the first side wall portion. The outer container includes a second bottom portion, a second side wall portion that extends in a second direction opposite to the first direction from the second bottom portion and forms a second open end portion, and a second vacuum layer continuously formed inside the second bottom portion and the second side wall portion. The outer container is fitted onto the inner container in such a manner that an inner surface of the second side wall portion and an outer surface of the first side wall portion face each other and forms a storage portion. The overlap region is formed in such a manner that the inner surface of the second side wall portion and the outer surface of the first side wall portion overlap each other.
