ABSTRACT:
A vacuum insulation panel and an insulation structure of a refrigerator applying the same are disclosed. The vacuum insulation panel comprises: a sealing cover (120) having an outermost layer exposed to the outside, a gas shielding layer stacked on the bottom surface of the outermost layer and formed of a thin metal sheet and a metal deposition film, and a heating-fusion bonding layer stacked on the bottom surface of the gas shielding layer and formed of an octane-base material; a core material (110) sealed by the sealing cover (120) in contact with the heating-fusion bonding layer, and provided with an extended insulation portion (130) some parts of which are extended between the bonding portions formed at the sealing cover (120); and a gas permeation preventing layer (125) formed on the sealing cover (120), so that can prevent an external air or moisture from penetrating into a vacuum insulation panel.
