ResumoWe study superconductivity mediated by the charge fluctuation in two-dimensional organic conductor β-(meso-DMBEDT-TTF)2PF6. We consider the extended Hubbard model on a weakly dimerized lattice, and solve the Eliashberg equations based on the random phase approximation. We found reentrant behavior of the checkerboard-type charge-ordered phase in the phase diagram, and the triplet superconductivity due to the charge fluctuation in the neighboring region. This results well agree with the experimental fact.
