Abstract
A formulation of the p-d-mixing model of oxide superconductors is presented by introducing composite operators that describe electronic excitations associated with the Cu-O covalent bond. A conduction band developing inside the charge-transfer gap with hole doping can be understood as the band formed by mixing among p and d electrons and these composite electronic excitations.
