PROBLEM TO BE SOLVED: To provide a method of manufacturing a vacuum insulation material capable of being subjected to processing such as bending.SOLUTION: A method of manufacturing a vacuum insulation material includes a fold line part formation step of forming a fold line part in an outer wrapping material, and a sealing step of coating a core material with the outer wrapping material formed with the fold line part and subsequently decompressing and sealing the inside. In the fold line part formation step, the fold line part is formed in the outer wrapping material in a state in which the two or more outer wrapping materials are stacked. 【課題】本発明は、屈曲等の加工が可能な真空断熱材の製造方法を提供することを主目的とする。【解決手段】本発明は、外包材に折り目線部を形成する折り目線部形成工程と、前記折り目線部が形成された前記外包材を用いて芯材を覆い、次に内部を減圧し密封する封止工程と、を有し、前記折り目線部形成工程にて、二枚以上が重ねられた状態の前記外包材に前記折り目線部を形成することを特徴とする真空断熱材の製造方法を提供することにより、前記目的を達成する。【選択図】図１
