An image sensor comprises a substrate (3) with a photoelectric conversion section (B) formed from an array of several individual photoelectric conversion elements (11) formed on the substrate. A drive circuit section (A) for sequentially reading output signals from the photoelectric conversion elements (11) is mounted on the substrate adjacent to photoelectric conversion section (B). The photoelectric conversion section (B) and the drive circuit section (A) are connected by conductive strips (4). The conductive strips (4) have capacitance adjustment conductive strips (4b) which correct the wiring length of the connecting conductive strips (4), and which are positioned underneath or close to said photoelectric conversion section (B). The adjustment conductive strips (4b) substantially equalise the stray capacitances of the connecting conductive strips (4).
