Abstract

To improve detectivity of a photoelectric conversion element (). A photoelectric conversion element including a pair of electrodes (), an active layer () provided between the pair of electrodes, and an intermediate layer () provided between the active layer and at least one of the pair of electrodes, in which the intermediate layer has a surface that is in contact with the active layer, the surface having a surface roughness having an absolute value greater than 0.22 nm but smaller than 1.90 nm, and in which the active layer is not less than 350 nm but not more than 800 nm in thickness.
