1. A light detection apparatus, comprising:
an effective region provided with a photodetector that is configured to:
detect irradiation light; and
perform photoelectric conversion; and
a peripheral region provided adjacent to the effective region; wherein
the photodetector has a stacked structure including
a first photoelectric conversion unit that os configured to:
detect light in a first wavelength range of the irradiation light; and
perform photoelectric conversion,
a second photoelectric conversion unit that is provided so as to overlap with the first photoelectric conversion unit, wherein the second photoelectric conversion unit is configured to:
detect light in a second wavelength range of the irradiation light; and
perform photoelectric conversion, and
a first optical filter that is provided between the first photoelectric conversion unit and the second photoelectric conversion unit and through which the light in the second wavelength range transmits more easily than the light in the first wavelength range, and
the peripheral region is provided with a second optical filter through which the light in the second wavelength range transmits more easily than the light in the first wavelength range.
