A secondary emissive electrode for image intensifiers, cathode-ray tubes and the like which comprises a plate of insulating material having two substantially parallel boundary surfaces on opposite sides thereof pierced by channels, the walls of which are secondary emissive, forming a high-density network of channels between two surfaces. The periphery of this plate has at least two regions one opposite the other relative to the center of the body with channels which are filled with a core material.
