Abstract

The sensitivity of an image sensor is improved. The image sensor includes a plurality of pixels and a light-blocking wall. The plurality of pixels included in the image sensor each includes a photoelectric conversion unit disposed on a semiconductor substrate and photoelectrically converting incident light that is irradiated, and an on-chip lens that focuses the incident light onto the photoelectric conversion unit. The light-blocking wall included in the image sensor is disposed adjacent to the semiconductor substrate at a boundary between the plurality of pixels and configured such that a side of the light-blocking wall that is irradiated with the incident light has a tapered-shape cross-section, the light-blocking wall blocking the incident light.
