  On a basis of earlier substantiated expression for effective potential of
electron-electron attraction in metals the assumption of an opportunity of
formation of classically bound pairs is put forward. It was shown that in
distinction from the Cooper pair, the energy of the electron pair in this
approach is negative in the centrum of mass of the pair. This fact changes the
pattern of the superconductivity phenomenon in the proposed model. First, the
gap in the one-particle spectrum appears due to the effect of a "mean field" on
the energy of electron state from the side of occupied states, the nearest
neighbors over the momenta grid. Second, the condensate is formed by electron
states with energies below that of the gap edge. No Bose condensation does
occur in the system proceeding from the proposed model. In quasi-classical
approximation Londons' hypothesis is substantiated.
