Abstract: An insulated container of paper which does not feel hot to the touch even when a user holds a trunk portion thereof in a hot water-containing state. The trunk portion has a doubly-walled structure with an insulating space provided between two wall members thereof. The doubly-walled insulating space-retaining structure is formed, as shown in FIG. 2, by inwardly curling both end portions of a cylindrical member and firmly fitting the resultant cylindrical member around an outer surface of a trunk portion of an inner container body. This structure results in a container capable of being manufactured at a low cost and having a high insulating capability and a high grasping resistance.
