Abstract
The present disclosure relates to a photodetection device and an electronic apparatus that allow for reducing surface reflection from an on-chip microlens and suppressing deterioration of image quality. Provided is a photodetection device including: a plurality of pixels that have photoelectric conversion units; on-chip microlenses that are formed in such a way as to correspond to the individual pixels; and an antireflection film that is formed on a surface of the on-chip microlens, in which the antireflection film is constituted by a stacking of: a first inorganic film that is formed by a metal oxide film; and a second inorganic film that is formed on a surface of the first inorganic film and has a lower refractive index than the first inorganic film. The present disclosure can be applied to, for example, a CMOS solid-state imaging device.
