PURPOSE:To achieve increased tolerance for positional shifts by forming V-shaped areas slanting relative to the longer sides of the scanning area in a signal-drawing low-resistance electrode which is installed on the peripheral area of a photoelectric conversion film formed on the inner surface of the face plate. CONSTITUTION:A signal-drawing target pin 2 and a transparent conductive film 3, which constitutes a photoelectric conversion surface, and installed on a face plate 1. A pin-lead-type camera tube is produced by forming a low- resistance electrode 4', consisting of a frame-like metallic vapordeposition film having V-shaped patterns 4a, on the peripheral area of the transparent conductive film 3 by vapor deposition: the V-shaped patterns 4a are formed by folding the pin-2-side area and its opposite area of the frame-like film toward its center by slant angles of at least 8 deg.. Owing to the above structure, it is possible to produce tolerance for the positional shift between a scanning area 5 and the electrode 5' and for that between the scanning area 5 and the glass chip. Furthermore, it is also possible to reduce the incidence of light reflected by the electrode 4' upon the scanning area 5. |
