Abstract: A method of manufacturing a target plate for a color television camera tube comprising a face plate including a fiber plate and a photoconductive target electrode having nonconductive portions of a stripe shape and provided on the inner surface of the face plate, comprising the steps of successively forming a transparent conductive film and a photoresist film on the inner surface of the face plate, setting an optical mask on the outer surface of the face plate, irradiating ultraviolet rays on the photoresist film through the photomask and the face plate to selectively expose the photoresist film to the ultraviolet rays and developing the photoresist film to obtain an apertured photoresist film to form the nonconductive portions.
