Abstract
Photoelectric conversion apparatus including semiconductor layer includes pixel array region and peripheral region. The semiconductor layer has first and second faces. Each pixel includes first semiconductor region of first conductivity type arranged on the first face side and second semiconductor region of second conductivity type arranged on the second face side, and predetermined voltage causing avalanche multiplication operation is supplied between the first semiconductor region and the second semiconductor region. The peripheral region includes third semiconductor region of the first conductivity type arranged on the first face side, fourth semiconductor region of the second conductivity type arranged apart from the third semiconductor region, and fifth semiconductor region of the first conductivity type arranged, close to the third semiconductor region, between the third semiconductor region and the fourth semiconductor region.
