Disclosed are an integrated wiring module for a refrigerator which is capable of simplifying the wiring of a refrigerator by integrating the various power lines and signal lines conventionally necessary to control a refrigerator into only one line, and a refrigerator having a simplified wiring structure adopting the same. The refrigerator includes integrated wiring modules provided at a refrigerator door connected to a main body board and to each actuator means, wherein the integrated wiring modules are connected to each other only through AC power lines so as to control the door and the respective actuator means, thereby being capable of achieving a door-side zero clearance and sliminess by simplifying the wiring within the refrigerator, reducing an error rate or failure rate which may arise due to the wiring, enhancing the insulating effect by reducing the number of wirings passing through insulation, and reducing the size of a main body board of the refrigerator to thereby increase the capacity of the inner space as by much as the reduced size.
