Acceleration of electrons in a relativistic laser pulse interaction with a nanowire is studied. Using numerical 2D simulations, characteristics of accelerated electrons are found for the nanowire targets. It is shown that, depending on the laser and target parameters, the maximal energy of electrons can be increased by more than twenty times in comparison with the energy of the electrons accelerated by a plane wave with the same amplitude. Parameters of the distribution in space for the accelerated electrons are determined, including the maximal density of the bunches and the total charge of the electron jet. Also, the dependences of the maximal electron energy on time of acceleration and diameter of the laser beam are evaluated.
