PROBLEM TO BE SOLVED: To provide a refrigerator which secures heat insulation performance and intensity of a heat insulation box.SOLUTION: A refrigerator includes: a protrusion part 450 formed on a back wall at a corner part of a side wall 790 of a refrigerating chamber and the back wall of the refrigerating chamber, and for protruding to a front side; a recess part 440 dented to a rear side with respect to the protrusion part 450 and formed on the back wall; and a vacuum heat insulation material 400 provided between an inner box 750 for forming an inner surface of the back wall and an outer box 710 for forming an outer surface of the back wall or between the inner box 750 for forming the inner surface of the side wall 790 and the outer box 710 for forming the outer surface of the side wall 790. The vacuum heat insulation material 400 is arranged so that at least one part is overlapped with the protrusion part 450, and at the protrusion part 450, the vacuum heat insulation material 400 is integrated with the inner box 750 and the outer box 710.SELECTED DRAWING: Figure 4 【課題】断熱箱体の断熱性能と強度を確保した冷蔵庫を提供する。【解決手段】冷蔵室の側壁７９０と冷蔵室の背面壁とのコーナー部の背面壁に形成され前面側に突出する凸部４５０と、凸部４５０に対して後方側に凹んだ背面壁に形成された凹部４４０と、背面壁の内面を形成する内箱７５０と背面壁の外面を形成する外箱７１０との間、あるいは、側壁７９０の内面を形成する内箱７５０と側壁７９０の外面を形成する外箱７１０との間、に設けられた真空断熱材４００と、を備え、真空断熱材４００は、凸部４５０と少なくとも一部が重なるように配置され、凸部４５０では真空断熱材４００が内箱７５０および外箱７１０と一体にされている。【選択図】図４
