A contact-type color image sensor in which pixel electrodes are linearly provided in a main scanning direction and three (or four) rows thereof are arrayed in a subscanning direction, color filters for color-separating are provided to oppose the pixel electrodes, an amorphous semiconductor film is formed on the pixel electrodes, and a common transparent electrode is formed on the amorphous semiconductor film. This color image sensor allows color-separation in the subscanning direction to maximize the areas of pixel electrodes.

A contact color image sensor characterized by comprising: pixel electrodes which are arranged on a substrate in a main scanning direction to form two outer rows and at least one inner row disposed between said outer rows in a subscanning direction each of said pixel electrodes of the inner row being formed to have a larger area than each one of said pixel electrodes of the outer rows; connecting electrodes, formed to be coplanar with said pixel electrodes, for leading out the outer two rows of said pixels electrodes in opposite directions and for leading out said at least one inner row of said pixel electrodes so as to extend between two adjacent ones of said pixel electrodes; an amorphous semiconductor film uniformly formed on said pixel electrodes and the portions of said connecting electrodes adjacent thereto; a common transparent electrode formed on said amorphous semiconductor film; a light-shielding film formed on an entire surface of said common transparent electrode except for portions over said pixel electrodes; and color filters, provided at positions over said pixel electrodes.
