In an insulator including an adsorbent configured to adsorb gas, an initial adsorption performance of the remaining gas inside the insulator using the adsorbent and a long-term adsorption performanceof gas introduced into the insulator from the outside are improved so that the short-term performance and the long-term performance of the insulator can be simultaneously improved. An adsorbent that is a first part of an adsorbent included in a vacuum insulator is accommodated in a first space formed with an inside surface of a container, and an adsorbent that is a second part of the adsorbent isdispersed into a second space formed with an inside surface of an outer envelope and an outside surface of the container.
