Abstract
Abstract An image sensor includes a photoelectric conversion unit, a charge storage unit (16), a switch unit (17,18), and a wiring unit (19), all of which are formed on a single substrate. A capacitor of the charge storage unit is formed at the same substrate position as that of a pattern of said wiring unit.
