ABSTRACT:
A method for manufacturing an image pickup tube target is disclosed, in which, in evaporating a porous Sb.sub.2 S.sub.3 film in a low pressure insert gas, the amount of pre-evaporation of Sb.sub.2 S.sub.3 is decreased as the number of times of repetitive use of an evaporation boat increases in which Sb.sub.2 S.sub.3 is placed for evaporation, whereby an Sb.sub.2 S.sub.3 film having a given porosity is formed.
