[Problem] Provided is an insulated container capable of applying a coating on the inner surface of the inner container, which has excellent abrasion resistance and corrosion resistance, and prevents adhesion of contaminants and odors. [Solution means] Having an outer container 2 and an inner container 3 made of metal with an open end, and the open ends of the outer container 2 are joined to each other while the inner container 3 is accommodated inside the outer container 2 In addition, as a heat insulating container 1 in which a vacuum heat insulating layer 4 is provided between the outer container 2 and the inner container 3, an intermediate layer and a diamond-like carbon (DLC) layer are formed on the inner surface of the inner container 3. , Are sequentially stacked. |
