ABSTRACT:
An image pick-up tube has a photoelectric conversion target including a transparent substrate, and a transparent electrode and a photoconductive layer formed on the transparent substrate. An electron beam is scanned on the photoelectric conversion target. A first electrode is formed on a beam scanning surface of the photoconductive layer so as to be segmented in stripe or grid with its electrode segments electrically connected to each other. A second electrode is formed on the first electrode through an insulating layer with its electrode segments electrically connected to each other. An insulating layer may be interposed between the first electrode and the photoconductive layer.
