2-color QCD at finite temperature T and chemical potential \mu is revisitedin the strong coupling limit on the lattice. The phase structure in the spaceof T, \mu and the quark mass m is elucidated with the use of the mean fieldapproximation and the large dimensional expansion. We put special emphasis onthe interplay among the chiral condensate, the diquark condensate and the quarkdensity in the T-\mu-m space. Qualitative comparison is made between ourresults and those of recent Monte-Carlo simulations in 2-color QCD.Comment: To appear in the Proceedings of the International Conference on Finite Density QCD at Nara, Japan, July 10-12, 200
