In this article we review essential natures of superconductivity in strongly correlated electron systems from a universal point of view. Here we consider materials such as high- cuprates, BEDT-TTF organic superconductors, ruthenate SrRuO, and heavy fermion superconductors. After the review of experimental results, we explain the formalism to discuss superconducting properties of strongly correlated electron systems based on the Dyson-Gor'kov equations. Then, we introduce theoretical retults on cuprates, organics, ruthenate, and heavy fermion superconductors in this order.
