Abstract: Let $ X \times Y$ be the product of a compact space $ X$ and a metric space $ Y$. We consider a continuous closed image $ Z$ of $ X \times Y$. Moreover, we consider a closed subspace $ R$ in $ X \times Y$ which is a neighborhood retract of it. It is proved in this paper that $ Z$ (respectively, $ R$) is a Lašnev (metrizable) space iff all compact subspaces of $ Z\left( R \right)$ are metrizable.
