Abstract
Provided is a photoelectric conversion device including: at least one charge holding portion including a first semiconductor region of a first conductivity type and configured to hold signal charges based on incident light; and an avalanche photodiode including a second semiconductor region of the first conductivity type, in which the signal charges are transferred from the first semiconductor region to the second semiconductor region via a third semiconductor region of a second conductivity type that is different from the first conductivity type, a fourth semiconductor region of the first conductivity type, and a fifth semiconductor region of the second conductivity type in this order.
