PROBLEM TO BE SOLVED: To provide a laminate for vacuum heat insulation material in which laminate strength and seal strength do not deteriorate even when foamed plastic is used as a thermal fusion layer of the laminate, in the laminate for vacuum heat insulation material, and a vacuum heat insulation material using the same.SOLUTION: A laminate for vacuum heat insulation material is used for a vacuum heat insulation material in which a heat insulation core material is coated by the laminate for vacuum heat insulation material, and in which the inside is brought into a vacuum state by degassing. In the laminate for vacuum heat insulation material, the laminate is constituted at least by a gas barrier layer and a thermal fusion layer, and the thermal fusion layer is constituted by an extrusion resin layer, a foamed plastic sheet and a thermal fusion film.SELECTED DRAWING: Figure 1 【課題】真空断熱材用積層体において、発泡プラスチックを積層体の熱融着層として用いた場合においても、ラミネート強度およびシール強度の低下することのない、真空断熱材用積層体およびそれを用いた真空断熱材を提供することを課題とする。【解決手段】断熱芯材を真空断熱材用積層体で被覆し、内部を脱気し真空状態とした真空断熱材に用いられる真空断熱材用積層体であって、積層体が少なくともガスバリア層および熱融着層とから構成され、該熱融着層は押し出し樹脂層、発泡プラスチックシート、および熱融着フィルムとから構成されることを特徴とする真空断熱材用積層体である。【選択図】図１
