PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material capable of improving recyclability, and to provide a cold storage and a water heater which employ the vacuum heat insulation material.SOLUTION: In a vacuum heat insulation material, a core material being a fiber assembly and a gas adsorption agent are packaged by an external capsule material having a gas barrier property, and the inside of the external capsule material is vacuumed and sealed. The gas adsorption agent is constituted by at least one type of component constituting the core material, or a compound of the one type of component and a hydroxyl group. 【課題】リサイクル性を向上できる真空断熱材、この真空断熱材を用いた冷蔵庫および給湯器を提供する。【解決手段】繊維集合体である芯材と、ガス吸着剤とを、ガスバリア性を有する外包材で包み、前記外包材の内部が減圧されて封止されて構成され、ガス吸着剤は、芯材を構成する少なくとも一種の成分、又は該成分と水酸基との化合物で構成した真空断熱材。【選択図】図４
