Disclosed are a vacuum heat insulating material that has an improved structure for heat insulating property and durability improvement, a method for manufacturing a vacuum heat insulating material, and a refrigerator including a vacuum heat insulating material. The vacuum heat insulating material includes: a core material; a first outer surface material disposed at the outer side of the core material; a blocking layer placed between the core material and the first outer surface material and attached to the first outer surface material to be integrated with the first outer surface material; and a second outer surface material greater in thermal conductivity than the first outer surface material, coupled with the first outer surface material, and having an accommodating space therein to accommodate the core material and the blocking layer. The first outer surface material and the second outer surface material may be attached to each other by welding or adhesion to form an extending portion extending to the outside from the accommodating space. 단열성 및 내구성이 향상되도록 개선된 구조를 가지는 진공단열재, 진공단열재의 제조방법 및 진공단열재를 포함하는 냉장고를 개시한다. 진공단열재는 심재(Core Material), 상기 심재의 외측에 배치되는 제 1외피재, 상기 심재 및 상기 제 1외피재 사이에 배치되고, 상기 제 1외피재와 일체를 이루도록 상기 제 1외피재에 접착되는 차단층 및 상기 제 1외피재보다 큰 열전도도를 가지고, 상기 제 1외피재와 결합하여 내부에 상기 심재 및 상기 차단층이 수용되는 수용공간을 형성하는 제 2외피재를 포함하고, 상기 제 1외피재 및 상기 제 2외피재는 융착 또는 점착에 의해 서로 접착되어 상기 수용공간의 외측방향으로 연장되는 연장부를 형성할 수 있다.
