• The superconductivity mediated by antiferromagnetic spirn-fluctuations (AFSF) isstudied in the quasi-one-dimensional Hubbard model. The superconducting transi-tion temperature and the momentum dependence of the order parameter arecalculated numerically. An effect of the long-range ( >>the lattice constant) AFSF is ex-amined. The obtained phase diagram is compared with that of the organic supercon-ductors (TMTSF).X and (DMET).X, and some qualitative agreements between thetheory and experiments are obtained.
