PROBLEM TO BE SOLVED: To improve recycling properties by dispensing with an aluminum tape attached to a radiation pipe and to prevent the deformation of the appearance of a refrigerator in a refrigerator-freezer. SOLUTION: In this refrigerator having a vacuum heat insulating material 105 closely kept into contact with an outer casing 102 and having a recessed groove on an outer casing 102 face, and the radiation pipe 120 disposed in the recessed groove 121 of the vacuum heat insulating material 105, the radiation pipe 120 is disposed in the recessed groove 121 of the vacuum heat insulating material 105, then the vacuum heat insulating material 105 is attached to the outer casing 102, and urethane is charged, thus air existing in a clearance is removed, volumetric expansion and contraction caused by ambient temperature fluctuation can be reduced, a load applied to the outer casing 102 of the refrigerator can be reduced, and the deformation can be prevented.
