Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material that can maintain stable heat insulation performance for a long term without largely impairing heat insulation performance over time, and can be used as a heat insulation material of a structure.SOLUTION: A vacuum heat insulation material 1 vacuum-packaged doubly includes: an internal vacuum heat insulation material 4 comprising a core material 2, and an inner covering material 3 covering the core material 2, formed by decompressing and sealing its inside and having gas barrier performance; and an outer covering material 5 covering the internal vacuum heat insulation material 4, formed by decompressing and sealing its inside and having gas barrier performance. The outer covering material 5 covers the internal vacuum heat insulation material 4 by thermally welding one sheet of a film having gas barrier performance. 【課題】本発明は、経時で大幅に断熱性能が損なわれることなく、安定した断熱性能を長期間維持できる真空断熱材であって、建築物の断熱材として用いることができる真空断熱材を提供することを目的とする。【解決手段】本発明の２重に真空包装された真空断熱材１は、芯材２と、前記芯材２を被覆し、かつ内部を減圧密封して形成されるガスバリア性を有する内被材３とからなる内部真空断熱材４と、前記内部真空断熱材４を被覆し、かつ内部を減圧密封して形成されるガスバリア性を有する外被材５からなり、前記外被材５は、１枚のガスバリア性フィルムを熱溶着することで、前記内部真空断熱材４を被覆していることを特徴とする。【選択図】図１
