The results obtained in a study of the frequency and temperature dependences of the ac electrical conductivity of FeIn_2Se_4 single crystals are presented. It is found that the law σ ~ f ^ S (0.1 ≤ S ≤ 1.0) is obeyed for electrical conductivity in the 295–375 K temperature range at frequencies of 2 × 10^4–10^6 Hz. It shown that the frequency dependence of the conductivity in an FeIn_2Se_4 single crystal can be accounted for in terms of the multiplet model, and, consequently, the conductivity in these single crystals is characterized by the band-hopping mechanism.
