<P>PROBLEM TO BE SOLVED: To provide a refrigerator capable of preventing the occurrence of poor appearance. <P>SOLUTION: The refrigerator includes: a heat insulating casing 10 comprising an inner casing 12, an outer casing 11 made of metal and a foam heat insulator filling a space between the inner casing and the outer casing; a heat radiation pipe 33, which is extended in one direction and arranged into a plurality of parallel lines with both ends meandering, and arranged in contact with an inner surface of the outer casing 11, and which has an extension 33a in one end extending outside the heat insulating casing 10; and a vacuum heat insulator 21, which comprises a core material 25 covered with a cladding 26 and has a plurality of grooves 22 arranged in parallel where the inner pressure is reduced and the heat radiation pipe 33 is to be fitted, and which is mounted on the inner surface of the outer casing 11. A communication path 43a that communicates the outside of the heat insulating casing 10 and the grooves 22 is formed in the periphery of the extension 33a to communicate the grooves 22 adjoining to each other in the parallel arrangement direction in a region other than the grooves 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
