Abstract

Disclosed is a refrigerator capable of minimizing generation of undercuts when manufacturing components of an inner case by injection molding. The refrigerator includes an inner case forming a storage compartment, and comprising a plurality of plates formed by injection molding; an outer case coupled to an outside of the inner case to form an external appearance; and an insulation disposed between the inner case and the outer case. A rear plate corresponding to one of the plates comprises: a drain hole formed through the rear plate to discharge water inside the inner case to the outside of the inner case; an inclined surface inclined downward toward the drain hole to allow water inside the inner case to flow to the drain hole; and an undercut prevention surface disposed below and spaced apart from the inclined surface, and forming a portion of an outer surface of the rear plate.
