<p>PROBLEM TO BE SOLVED: To provide a core material for a vacuum insulation material, which can be easily encapsulated without using any nonwoven fabric or the like, which can prevent the pin hole or crack to occur in an outer packaging material film before and after the encapsulation, and a vacuum insulation material using the vacuum core material as a core material.SOLUTION: A core material for a vacuum insulation material is characterized: by composing at least fine particles, a binding agent and cellulose fibers; by containing said fine particles by 10 weight% to 60 weight%; and by having a sheet shape. Moreover, the film thickness is made 0.05 mm or more and 2 mm or less. On the other hand, the porosity of the fine particles can be 70% or more.</p> |
