To provide a vacuum heat insulating body that can maximize adsorption capacity to maintain high heat insulating performance for a long time, without deactivating a gas adsorbing material that keeps high heat insulating performance of a vacuum heat insulating material highly reliable for a long time.SOLUTION: A vacuum heat insulating body comprises an outer packaging material made of a resin sheet, a core material included in the outer packaging material, and a gas adsorption device. The gas adsorption device is composed of: a vacuum sealed container including a gas adsorbing substance that adsorbs various kinds of gas; an opening pin that opens the vacuum sealed container by a physical load from the outside; and a load-bearing spacer that suppresses the displacement of the opening pin to a predetermined amount or less.SELECTED DRAWING: Figure 3A 【課題】本開示は、真空断熱材の断熱性能を長期に亘って信頼性高く保つ気体吸着材を失活させることなく、その吸着能力を最大限に発揮させて、高い断熱性能を長期的に維持することが可能な真空断熱体を提供する。【解決手段】本開示における真空断熱体は、樹脂シートからなる外包材と、外包材に内包される芯材と、気体吸着デバイスを備え、気体吸着デバイスは、各種気体を吸着する気体吸着物質を内包する真空密閉容器と、外部からの物理的な荷重により真空密閉容器を開封する開封ピンと、開封ピンの変位を所定量以下に抑える耐荷重スペーサーから構成されている。【選択図】図３Ａ
