It has been shown that the height of the nanoproduct deposited in the case of electrodeposition under conditions of the template synthesis into pores of variable (in height) diameter becomes a nonlinear function of the passed charge. The results of the experimental research data, which are indicative of the presence of such effects at the electrodeposition of silver and copper into membranes from Al2O3, have been presented. The analysis of these results shows that the nonlinearity results from the noncylindricity of the pores only in the layers of the membranes close to the initial electrode surface or when the pores represent the internal surface of a rotation body with a weak dependency of the radius on the pore height.
