1. A photoelectric conversion apparatus comprising:
a first substrate including an avalanche photodiode; and
a second substrate,
wherein the first substrate and the second substrate are stacked on each other,
the photoelectric conversion apparatus further comprising:
at least one temperature detection unit arranged in at least one of the first substrate and the second substrate and having an output characteristic depending on a temperature; and
a temperature value generating circuit arranged outside the first substrate and configured to convert output from the temperature detection unit into a temperature value signal that is a signal indicating temperature information.
