We investigate the electronic state of the 11 band d-p model on the two-dimensional triangular lattice simulating a CoO 2 plane in the layered cobalt oxides such as Na x CoO 2 and Na x CoO 2 AE yH 2 O. The tight-binding parameters are determined so as to fit the LDA band structure. Using the slave b
