Abstract
What is provided is a light detection apparatus along with a method of manufacturing the same, the apparatus being adapted to improve both the light blocking effect between pixels and the photoelectric conversion efficiency of each pixel. The light detection apparatus of this disclosure includes a substrate, a plurality of photoelectric conversion units provided inside the substrate, and a light blocking film provided at least between the photoelectric conversion units inside the substrate. The light blocking film includes a first film provided inside the substrate and a second film provided inside the substrate via the first film. The light absorption rate of the second film is higher than that of the first film.
