Cubic conductive copper oxide ceramics which are represented by the following formula I: (MxCuy)7OzAw I wherein M represents at least one element selected from the group consisting of In, Sc, Y, Tl, and Ga, A represents Cl, NO3, or Cl and NO3, x+Y is a value of 1, x/y is a number of 0 to 10, z is a number of from 6 to 8, and w is a number of from 1 to 9, and processes for producing same by mixing at least one nitrate and/or chloride of a metal selected from the group consisting of In, Sc, Y, Tl, and Ga, with copper nitrate and/or copper chloride, and firing the mixture at from 200 DEG to 600 DEG C. The copper oxide ceramics are preferably used as electrodes in various fields, heat emiters and also as a material for producing superconductors.
