Abstract
Provided is an imaging device that includes a pixel, a pixel circuit, a light-shielding wall, a through electrode, and a protrusion. The pixel includes a first photoelectric conversion unit and a second photoelectric conversion unit. The first photoelectric conversion unit is adjacent to the semiconductor substrate and performs photoelectric conversion of incident light. The second photoelectric conversion unit is in the semiconductor substrate and performs photoelectric conversion of the incident light transmitted through the first photoelectric conversion unit. The pixel circuit generates an image signal based on charges generated through photoelectric conversion of each of the first photoelectric conversion unit and the second photoelectric conversion unit. The light-shielding wall shields incident light. The through electrode is on the light-shielding wall, and transmits charges generated through photoelectric conversion in the first photoelectric conversion unit to the pixel circuit. The protrusion is an end of the light-shielding wall.
