Abstract: The present invention relates to an ice cooler, and in particular to an improved ice cooler capable of achieving an optimum cooling state in such a manner that an engaging groove of an inner container having a certain bottle (referred to as a Soju (Korean liquor) bottle, a wine bottle, etc.) is engaged with an engaging protrusion of an outer container having ice cubes, and a molten ice water does not directly contact with an outer side of a bottle mounted in the inner container. The ice cooler includes a plurality of lamps that are provided on an outer surface of the outer container and are turned on and off using a power of a charging battery, wherein said inner container includes an opened part in an upper side of the same and a sealed part at an outer circumferential surface of a lower side of the same with a certain height, and a net shaped part integrally connected with an upper side of the sealed part is formed with a certain height.
