Let X be a metrizable space and \rm Comp(X) be the hyperspace consisting of non-empty compact subsets of X endowed with the Vietoris topology. In this paper, we give a necessary and sufficient condition on X for \rm Comp(X) to be homeomorphic to a non-separable Hilbert space. Moreover, we consider the topological structure of pair (\rm Comp(X),\rm Fin(X)) of hyperspaces of X and its completion X, where \rm Fin(X) is the hyperspace of non-empty finite sets in X.
