We report on electron identification methods and their performance in the Belle experiment at the KEK-B asymmetric B-Factory $e^{+} e^{-}$ storage ring. Electrons are selected using a likelihood approach that takes information from the electromagnetic calorimeter, the central drift chamber, and the silica aerogel Cherenkov counters as input. We achieve an electron identification efficiency of $(92.4 \pm 0.4)%$ with a $\pi^{\pm}$ fake rate of $(0.25 \pm 0.02)%$ for the momentum range between 1.0 GeV/$c$ and 3.0 GeV/$c$ in laboratory frame.
