Abstract: An ice maker and a refrigerator having the ice maker are disclosed. The ice maker includes: an ice making tray having a plurality of cells; an ejector disposed at one side of the ice making tray and separating ice within the cells; and a driving motor installed at an upper side of the ice making tray and providing a driving force to the ejector. The size of the ice making tray can be increased in a lengthwise direction to increase the ice making capacity. The ice maker can be suitably installed at an inner side of a door where a horizontal width can be hardly changed.
