Zusammenfassung:	Realized is a solid-state imaging device capable of achieving both a finer pixel size and high light receiving efficiency with an excellent image characteristic. A high concentration p-well layer (5) is partially formed in the interior of a semiconductor substrate (1) centering on a region under a STI (6), and a photoelectric conversion layer (9a, 9b) is formed so as to extend to a region under a gate electrode (10a, 10b). Furthermore, a salicide region (12a, 12b) covers only a portion of a surface of the gate electrode (10a, 10b) and is formed at a position closer to a side at which a drain region (13) is provided. Thus, an incident light is allowed to pass through a portion, included in the surface of the gate electrode (10a, 10b), on which the salicide region (12a, 12b) is not formed, and then to be further incident on the photoelectric conversion layer (9a, 9b) extending to the region under the gate electrode (10a, 10b).
