Claim:
1. A method of manufacturing a refrigerator, comprising: preparing an inner case including an ice making chamber and an opening formed through at least a wall of the inner case and communicating with the ice making chamber; preparing an outer case to be coupled to an outside of the inner case; preparing a refrigerant pipe assembly including a refrigerant pipe having a section that is disposed in the ice making chamber so as to supply cooling energy to the ice making chamber, and a refrigerant pipe insulator including a first insulator section and a second insulator section which together insulate at least some of the section of the refrigerant pipe which is disposed in the ice making chamber; inserting the refrigerant pipe assembly into the opening of the inner case in an inward direction from the outside of the inner case such that a portion of the refrigerant pipe insulator is disposed in the ice making chamber, and a remaining portion of the refrigerant pipe insulator is disposed between the inner case and the outer case; and foaming a body insulator between the inner case and the outer case, thereby supporting the remaining portion of the refrigerant pipe insulator by the body insulator and, wherein the preparing of the refrigerant pipe insulator comprises:
