Recent states of researches on various interactions of electrons with matter are reviewed from a unifying viewpoint for the energy region between 10 eV and several tens MeV. In the first half, elementary processes such as ionization, excitation, Auger effect, plasma excita-tion, collision with free electrons, nuclear scattering and bremsstrahlung, are outlined. In the latter half, multiple processes and penetration through thick layers of matter are treated. Problems remaining to be solved are also suggested.
