PROBLEM TO BE SOLVED: To provide a drink holder for hot/cold preservation, in which various kinds of canned drinks are securely held, sufficient heat insulation can be demonstrated by conduction efficiently the heat transfer. SOLUTION: A cold-energy element utilizing the Peltier effect is installed on a hollow base, on which a cylindrical hollow thermal insulation case is attached. A heat conductive body is provided in the inside of the thermal insulation case, in contact with the upper surface of the cold-energy element. In the inside of the heat conductive body, a canned-drink holder is provided, which is formed by winding spirally a heat-conductive spring plate.
