Vanishing of longitudinal mode of massive photon as photon mass goes to zero in gage-invariant electrodynamics, is investigated with help of examples; distinction between two forms of gage-invariant amplitudes is made in order to clarify this limit; conditions are obtained so that limiting process is smooth; results on equality of particle charge are obtained which are usually derived by means of Ward's identity.
