An imaging device includes a light shield that has light shielding walls and a plurality of light transmissive parts in a plurality of apertures between the light shielding walls and a light-receiving element layer in which a large number of light-receiving elements that perform photoelectric conversion corresponding to incident light inputted through the light transmissive parts of the light shield are arranged to acquire image information that has passed through optical elements that are different between the adjacent light transmissive parts. Further, the image information that passed through optical elements being different for every one of the light transmissive parts adjacent is acquired, and therefore, the sensor areas of the light receiving element is utilized effectively.
