Abstract: The definition of interval-valued metric spaces is introduced, according to the definition of compactness and their related equivalent relations in general topological spaces, the compactness and a set of equivalent relations of induced topological space by interval-valued metric are proved, the paracompactness of this induced topological space is discussed in the paper.

Key words: interval number, interval-valued metric space, compactness, paracompactness
