PURPOSE: A refrigerator insulator is provided to minimize void formed at the insulator and prevent deformation of inner case, by uniformly injecting foam material. CONSTITUTION: A refrigerator insulator comprises an inner case(14) having a barrier for sectioning freezing compartment and refrigerating compartment; and an outer case(12) having a plurality of foam material injection ports(12a,12b) arranged at the rear surface of the outer case so as to correspond to the barrier, and an additional foam material injection port(12c) arranged at the center of the lower end of the outer case. The foam material is injected uniformly and simultaneously, via injection ports, throughout the space formed between the inner case and the outer case, thus minimizing void formation occurring after completion of foaming process.
