Provided is a vacuum insulator such that the shape of the insulator is not disturbed by sealing in a small bag, and that prevents lowering of the degree of vacuum by air components, including oxygen, penetrating through the outer coating material. Specifically, provided is a vacuum insulator configured from a core material and an outer coating material that includes an oxygen absorbing layer that contains an oxygen absorbing resin. Additionally provided is a vacuum insulator configured from a core material and an outer coating material in which is included an oxygen absorbing resin wherein an unsaturated alicyclic structure serves as an oxygen absorbing site in the oxygen absorbing layer. |
