Summary:PROBLEM TO BE SOLVED: To enhance the heat insulating performance of a vacuum heat insulating material, and to suppress the deterioration of the heat insulating performance, with the elapse of time. SOLUTION: The vacuum heat insulating material 1 comprises a core material 4 composed of a fiber-system material of an inorganic fiber or an organic fiber, and having flexibility, an adsorbent 5 for adsorbing moisture or gas, and a sheathing material 2 for accommodating the core material 4 and the adsorbent 5, and vacuum-exhausts the inside of the sheathing material 2. The vacuum heat insulating material is constituted, in such a manner that: the adsorbent 5 is wrapped with a wrapping material 6 having gas barrier performance; a notch 7 which can make the outside and the inside of the wrapping material communicate with each other but does not penetrate the wrapping material is formed at the wrapping material 6; the notch 7 is opened by breakage caused by an external force applied to the notch 7; and the internal space of the wrapping material 6 communicates with the internal space of the sheathing material 2.
