We describe some specific quantum black hole model. It is pointed out that
the origin of a black hole entropy is the very process of quantum gravitational
collapse. The quantum black hole mass spectrum is extracted from the mass
spectrum of the gravitating source. The classical analog of quantum black hole
is constructed.Comment: 14 pages. Talk given at the Fifth Workshop on Quantum Field Theory
under the Influence of External Conditions, Leipzig, 10-14 Sept., 200
