Abstract
In a light receiving device, a light receiving element includes a first photoelectric conversion unit (PD) that converts light into electric charges, a first electric charge storage unit (MEM) to which the electric charges are transferred from the first photoelectric conversion unit, a first distribution gate, a second electric charge storage unit (MEM) to which the electric charges are transferred from the first photoelectric conversion unit, and a second distribution gate, in which the first and second distribution gates are provided at positions axially symmetric to each other with respect to a first center axis extending so as to pass through the center of the first photoelectric conversion unit, in a direction intersecting the column direction at a predetermined angle, when viewed from above the semiconductor substrate.
