Abstract: A photodetector includes a semiconductor substrate; a photoelectric converter in the semiconductor substrate; and a condenser light-transmissive and opposed to the photoelectric converter. The condenser includes: an inorganic material layer at least partially overlapping the photoelectric converter in a plan view; and an inorganic material layer covering the inorganic material layer and having a refractive index lower than a refractive index of the inorganic material layer.
