Abstract A vacuum heat-insulation material which comprises a core material for maintaining a vacuum space, an adsorbent for adsorbing moisture, and an encasing material that covers the core material and the adsorbent, the encasing material having been hermetically sealed so that the inside thereof is in a depressurized state, wherein the encasing material is configured of a surface-protective layer, a gas-barrier layer comprising at least two kinds of gas-barrier films, and a fusion-bonding layer, the at least two kinds of gas-barrier films having a difference therebetween in shrinkage through heating at 100°C for 2 hours or longer of 2% or less.
