Abstract: A heat insulating container enabling a reduction in man-hour and materials in production while sufficiently securing the strength of an external body on its bottom side. The container comprises a bottomed cylindrical container body and the external body formed of a foam resin sheet with thermal shrinkage properties and covering the peripheral wall of the container body to form a space between the peripheral wall and the external body. The external body comprises a tubular part opposed to the peripheral wall of the container body and an annular part extended from the bottom opening edge part, as a base end, in the tubular part. The annular part is characterized in that the tip side thereof is apart from the inner peripheral surface of the tubular part more than the base end part side thereof.
