Abstract
This thermal insulation material is provided with: thermal insulation layers, each of which has a porous structure having a skeleton that is composed of a plurality of particles connected with each other, while having pores inside and hydrophobic portions at least on the surface among the surface and the inside; and a pair of functional layers which are arranged on both sides of the thermal insulation layers in the thickness direction. The pair of functional layers have the same properties that include at least one of fire resistance and radiant heat dissipation properties.
