Abstract: The electric and thermoelectric properties of silver selenide in the temperature range of 4.2–300 K have been studied. The data obtained are interpreted within the theory of one-type carriers and Kane dispersion relation, with allowance for the character of electron-electron interaction. It is established that, for the concentrations $n\le$ 7.8 $\times$ 10$^{18}$ cm$^{-3}$, charge carriers are scattered by impurity ions at $T\le$ 30 K and by acoustic and optical phonons and point defects at $T\ge$ 30 K. Electron-electron interactions are found to be elastic at $T <$ 30 K.
