Therefore, even if there is a dimensional deviation of the heat dissipation duct 62 bent into a predetermined shape, it can be bent and deformed in the width direction by the curved portion 62c to absorb the dimensional error caused by the folding process. Therefore, even if the heat dissipating duct 61 is fixed to the outer casing 12, it is difficult to cause the bulging (conduit mark) of the outer casing 12 on the outer surface of the casing 16, so that the appearance of the refrigerator is not impaired. In the refrigerator 10 of the present embodiment, the bent portion 62c having the folded shape protruding from the rear portion of the top wall 16c is disposed at both end portions in the width direction of the top wall Me, so that the casing 16 can be disposed in the casing 16 Since the curved portion 62c having a temperature higher than the temperature in the refrigerator is disposed at a position where the heat insulating wall is thicker in the refrigerator, the heat of the curved portion 62c is less likely to leak to the inside of the refrigerator, and the heat insulating performance of the casing 16 can be improved. In addition, in the refrigerator 10 of the present embodiment, the vacuum heat insulating material 11 is disposed between the bent portions 6 2 c provided at both end portions in the width direction of the top wall 16c, so that the top wall 16 can be provided. The vacuum heat insulating material 11 is disposed in a wide range of the portion of the crucible that faces the storage space, so that the heat insulating performance of the casing 16 can be improved. Further, in the refrigerator 10 of the present embodiment, the side heat dissipation ducts 62a provided in the side walls 16a, 16b of the casing 16 are formed at the rear end portions of the side walls 16a, 16b on the side of the heat insulating space of the outer casing 12 Since the direction is a linear shape extending, the vacuum heat insulating material 15 can be disposed in a wide range of the side walls 16a and 16b of the casing 16, so that the heat insulating performance of the casing 16 can be improved. In other words, as shown in FIG. 7 of the comparative example of the present embodiment, when the side heat dissipation duct 62a is provided with the folded portion 65 that protrudes forward from the rear portion of the side wall 16a of the casing 16, it is necessary to avoid the folded portion. 65, a vacuum heat insulating material 15 is provided in the side walls 16a, 16b. However, in the present embodiment, since the side heat dissipation duct 62a has a linear shape (see Fig. 6), the vacuum heat insulating material 15 can be disposed in a wide range of the side walls 16a and 16b of the casing 16. According to the configuration in which the folded portion 65 is provided in the side heat dissipation duct 62a as shown in Fig. 7, it is necessary to ensure the bending radius of the duct. Therefore, the size of the folded portion 65 in the vertical direction must be increased to some extent. It is difficult to make the distance A from the upper end of the vacuum heat insulating material 15 to the upper end side 61a of the heat dissipation duct 61 disposed in the side wall i6a smaller than the distance B from the upper end side 61a to the outer box top plate 12b, but in FIG. In the present embodiment, the vacuum insulation from the side walls 16a, 16b can be made
