Title: Photo-electric conversion device with current fluctuation suppression

Abstract: A photo-electric conversion device comprises a pixel array in which a plurality of pixels, each including a photo-electric converter, are arrayed to form rows and columns; signal lines respectively corresponding to the columns of the pixel array; load transistors respectively corresponding to the signal lines; and capacitances respectively corresponding to the load transistors. Each signal line is connected to the pixels of the corresponding column. Each capacitance includes a first electrode and a second electrode. When viewed from a direction perpendicular to a light-receiving surface of the photo-electric converter, the first electrode is arranged within a region which is surrounded by (i) the adjacent signal lines which are arranged closest to each other, (ii) the pixel array, and (iii) a virtual line connecting end portions of the adjacent signal lines, so as to not overlap the adjacent signal lines.
