Abstract

A photoelectric conversion element provided in a semiconductor layer having first and second surfaces includes a first region of a first conductivity type, a second region of a second conductivity type closer to the second surface than the first region and forming a p-n junction with the first region, a third region of the first conductivity type closer to the second surface than the second region, a fourth region of the second conductivity type closer to the second surface than the third region, a fifth region of the second conductivity type between the third fourth regions, and a sixth region of the second conductivity type surrounding a region where the first, second, third, and fifth regions are disposed in a plan view. The fifth region has an area smaller than that of the third region in the plan view, and overlaps with the first region in the plan view.
