A vacuum insulation panel and to a method for manufacturing same. The method comprises: (a) a step of laminating a plurality of glass fiber boards to form a core, wherein the glass fiber boards are produced by a papermaking method using glass fiber dispersed in an inorganic binder; (b) a step of forming an outer cover having a structure in which a surface protection layer, a metal barrier layer, and an adhesive layer are laminated; (c) a step of producing a getter by packing quicklime (CaO) powder in a pouch; (d) a step of attaching the getter onto the core, or inserting the getter into the surface of the core; and (e) a step of forming the outer cover into a bag body, inserting the core from step (d) into the bag body, and sealing the bag body, thereby improving long-term durability of the vacuum insulation panel.
