Abstract
A vacuum heat-insulating material includes: an outer cover material; and a core material which is sealed in a tightly closed and decompressed state on the inside of the outer cover material. Outer cover material has gas barrier properties and satisfies at least one of a condition that a linear expansion coefficient is 80×10/° C. or lower when a static load is 0.05 N within a temperature range of −130° C. to 80° C., inclusive, a condition that an average value of a linear expansion coefficient is 65×10/° C. or higher when a static load is 0.4 N within a temperature range of −140° C. to −130° C., inclusive, a condition that an average value of a linear expansion coefficient is 20×10/° C. or higher when a static load is 0.4 N within a temperature range of −140° C. to −110° C., inclusive, and a condition that an average value of a linear expansion coefficient is 13×10/° C. or higher when a static load is 0.4 N within a temperature range of +50° C. to +65° C., inclusive.
