Abstract: In a color image pick-up tube using a silicon target plate as a photo-electric transducer, the main portion of the face plate is slightly elevated except at its peripheral annular portion to form a flat-topped convexity on which a color filter is formed and the peripheral protrusion of the silicon target plate is fastened to the peripheral annular portion of the face plate, so that the target area of the target plate is arranged in opposition to the color filter with a small gap left therebetween.
