The dielectric response of valence fluctuation compound Sm 3 Se 4 has been measured in the frequency range from 20 Hz up to 1 GHz. The resultant response of Sm 3 Se 4 is described by a superposition of two independent dispersions with the Cole-Cole type, which are given by the valence fluctuating state in Sm 3 Se 4 crystal with vacancies. The phase angle θ= 90° for the admittance of Sm 3 Se 4 at low temperatures leads the absence of free carrier like in an ideal capacitor. Similar behavior on Sm 2 Se 3 is also presented.
