A refrigerator having resin foam and a vacuum heat insulator between an outer box and an inner box adopts any one of the following configuration whereby it is possible to provide a refrigerator having an outward appearance, which is good in attractiveness, and effecting an efficient heat insulation. An outer surface of an outer box on which the heat insulator is arranged are set to have a center line average roughness (Ra) of 0.1 mu m or more, or the outer surface is set to have a glossiness of 80 or less; The heat insulator is stuck to an inner plate of a door which constitute a front surface; an intermediate member is provided between the heat insulator and the outer box to prevent deformation of the outer surface of the outer box; A radiating pipe is provided between the heat insulator and the outer box, and an air gap defined by the heat insulator and the radiating pipe is communicated to outside; A small hole is provided on a surface of the outer box on which the heat insulator is provided; The heat insulators are arranged on both side surfaces of an upper portion, a roof surface, a back surface, and a front surface to contact with the outer box, and on a bottom surface, both side surfaces of a lower portion, and surfaces which define a machine room provided in the lower portion to contact with the inner box; and The heat insulator having a radiating pipe assembled into a surface thereof, which contact with the outer box, are arranged inside the outer box.
