Exclusive J/{psi} electroproduction is studied in the framework of the analytic S-matrix theory. The differential and integrated elastic cross sections are calculated using the modified dual amplitude with Mandelstam analyticity model. The model is applied to the description of the available experimental data and proves to be valid in a wide region of the kinematical variables s, t, and Q{sup 2}. Our amplitude can be used also as a universal background parametrization for the extraction of tiny resonance signals.
