We report inelastic neutron scattering results for single-crystalline samples of PrFe$$_4$$P$$_{12}$$, which undergoes a transition from the heavy-electron phase to the antiferro-type nonmagnetic ordered phase. In contrast to the quasielastic magnetic response observed in the heavy electron phase, the well-defined inelastic peaks located at 1.5 and 3 meV are superimposed in the ordered phase. The maximum spectral intensity appears at the Brillouin zone center for the original $$Imbar{3}$$ structure, and the minimum spectral intensity appears at the zone boundaries including the ordering vector $$q_0$$ = (1,0,0). The spectra are consistent with the recently proposed staggered ordering of a Pr site with well-localized $$f$$-electrons and that with a Kondo-singlet-like state, which are represented as the totally symmetric state accompanied by the charge modulation of carriers.
