In the faceplate structure of image pickup tube having an organic coat, an inorganic transparent conductive film and an inorganic photoconductive film sequentially laminated on the central part of a transparent glass base, the inorganic transparent conductive film and the inorganic photoconductive film are formed so that they are non-porous in at least part of their respective sub-layers in the direction of lamination. Further, the transparent conductive film and the photoconductive film have a larger area than that of the organic coat so that they will completely cover the organic coat.
