  Lepton-flavor violation (LFV) is forbidden in the standard model but possible
in several new physics scenarios. In many of these models, the radiative decays
$\tau^{\pm}\rightarrow\ell^{\pm}\gamma$ ($\ell=e,\mu$) are predicted to have
the largest probability, making them apt channels to be probed by the Belle
experiment. The result of a search for LFV via
$\tau^{\pm}\rightarrow\ell^{\pm}\gamma$ using full data of the Belle experiment
corresponding to an integrated luminosity of 988 fb$^{-1}$ is reported. No
significant excess over standard model background predictions is observed and
the upper limits on the branching fraction, $\mathcal{B}(\tau^{\pm}\rightarrow
\mu^{\pm}\gamma)$ $\leq$ $4.2\times10^{-8}$ and
$\mathcal{B}(\tau^{\pm}\rightarrow e^{\pm}\gamma)$ $\leq$ $5.6\times10^{-8}$,
are set at 90% confidence level.
