Claim 7:
8. The element according to claim 1, wherein
the photoelectric conversion layer further includes a fourth partial region between the first partial region and the second partial region,
a change rate of a Sn concentration with respect to a positional change in a first direction in the fourth partial region is less than a change rate of a Sn concentration with respect to a positional change in the first direction in the first partial region,
the first direction is from the first conductive layer toward the second conductive layer, and
the change rate of the Sn concentration with respect to the positional change in the first direction in the fourth partial region is less than a change rate of a Sn concentration with respect to a positional change in the first direction in the second partial region.
