To provide a refrigerator capable of improving cooling efficiency to save energy.

In the refrigerator 1, a heat insulating case body 6 filled with a foamed heat insulating material 12 is arranged between an outer case 10 and an inner case 11. Reinforcement plates 13 having thermal conductivity higher than that of stainless steel is provided on inner faces of stainless steel sheets forming at least part of the outer case 10, and refrigerant pipes 14 where a refrigerant is made to flow are arranged on the reinforcement plates 13.
