A refrigerator including a main body provided with storage chambers, doors to open and close the storage chambers, upper hinge modules to enable one side of the upper end of each door to be rotatably installed on the main body. Main body hinge receipt parts are depressed on the upper surface of the main body to embed rear ends of the upper hinge modules in the upper surface of the main body and door hinge receipt parts are depressed on the rear surfaces of the doors to receive front ends of the upper hinge modules, and thus the main body is located at a height corresponding to the height of the doors, thereby allowing the main body provided with the storage chambers having a wider volume to be used in the refrigerator having a designated height.
