Vacuum heat-insulating material, and heat-insulting container, dwelling wall, transport machine, hydrogen transport tanker, and LNG transport tanker equipped with vacuum heat-insulating material

A heat-insulating container comprising:

• a heat-insulating structure body equipped with a vacuum heat-insulating material, the vacuum heat-insulating material including:
• an outer cover material including at least a resin component;
• and
• a core material which is sealed in a tightly closed and decompressed state on an inside of the outer cover material,
• wherein the outer cover material has gas barrier properties and satisfies at least one of (1) a condition that a linear expansion coefficient is 80×10−51° C. or lower when a static load is 0.05 N within a temperature range of −130° C. to 80° C., inclusive, (2) a condition that an average value of a linear expansion coefficient is 65×10−5/° C. or higher when a static load is 0.4 N within a temperature range of −140° C. to −130° C., inclusive, (3) a condition that an average value of a linear expansion coefficient is 20×10−5/° C. or higher when a static load is 0.4 N within a temperature range of −140° C. to −110° C., inclusive, and (4) a condition that an average value of a linear expansion coefficient is 13×10−51° C. or higher when a static load is 0.4 N within a temperature range of +50° C. to +65° C., inclusive, and
• wherein a substance is held in the heat-insulating container.
