<p><P>PROBLEM TO BE SOLVED: To prevent sudden reduction in the heat reserving/heat insulation effect even if a vacuum heat insulation material to be easily damaged and difficult in handling is damaged. <P>SOLUTION: Since the vacuum heat insulation material is a vacuum heat insulation material 1 of finely dividing a vacuum heat insulation part 2 into a plurality, the high heat reserving/heat insulation effect is held over a long period without largely reducing the heat insulation effect as a whole even if a vacuum state is broken in one heat insulation part, by finely dividing the vacuum heat insulation part into the plurality. This vacuum heat insulation material is also used without anxiety over a long period without risk of suddenly reducing the heat reserving/heat insulation effect. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
