We examine the propagation of a dark soliton in a nonlinear LC circuit which isequivalent to the Toda lattice. At first, we derive the nonlinear Schr6dinger equation todescribe a nonlinear wave of strong dispersion. It is shown theoretically that the waveof envelope is modulationally stable and propagates as a dark soliton, if the circuit isequivalent to the Toda lattice. In the experiment, it is confirmed that the dark soliton isgenerated from an initial wave and propagates stably in the circuit. The width of thesoliton agrees with the theory.
