A new approach to the theory of high‐Tc superconductivity in cuprate oxides is proposed, based on the possibility of superelectrons derived from inner closed shells in shrunken atoms induced by a strong screened attractive interaction between an electron and an ion. An electrostatic fluctuation connected with an electronic polarizability halts the breaking‐up of the pre‐existing pairs of electrons with antiparallel spins in the shells. The transport of superelectrons can be explained by the virtual tunneling.
