A vacuum heat insulator comprising an oxygen absorbent which does not require water to absorb oxygen, a dehydrating agent and an acidic gas absorbent. In a preferred embodiment, the oxygen absorbent comprises (i) at least one of an unsaturated fatty acid compound and a chain hydrocarbon polymer having an unsaturated group as a main component, and (ii) an oxygen absorbent accelerator. When arranged in a vacuum container or vacuum package, the vacuum heat insulator absorbs oxygen, water and acidic gases which permeate the vacuum container or package or which are generated within the vacuum container or package, to thereby maintain the degree of vacuum and good thermal insulating properties.
