The problem on crossover between the Cooper-pair condensation and the Bose-Einstein condensation of “di-electronic molecules” in two-dimensional superconductors is discussed. a result based on the Nozières and Schmitt-Rink formalism is reviewed and a preliminary result beyond their formalism is presented. In the latter, effect of repulsion between electron pairs due to the exchange effect among constituent electrons plays a crucial role.
