In the Nonlinear Schrödinger model, the correspondence between classical soliton and its quantum field theory is investigated. It is shown explicitly that moving soliton as well as soliton at rest arise as the matrix elements of a field operator in the limit n→∞, where n is the particle number making the bound state.
