Abstract The \PAMELA\ experiment is collecting data since 2006; its results indicate the presence of a large flux of positron with respect to electrons in the \CR\ spectrum above 10 GeV. This excess might also be originated in objects such as pulsars and microquasars or through dark matter annihilation. Here the electrons and positrons events collected by \PAMELA\ have been analized searching for anisotropies. The analysis is performed at different angular scales and results will be presented at the conference
