1. A photoelectric conversion element comprising:
a first electrode;
a second electrode disposed to be opposed to the first electrode; and
a photoelectric conversion layer provided between the first electrode and the second electrode, the photoelectric conversion layer including a chromophore, fullerene or a fullerene derivative, and a hole-transporting material,
the chromophore and the fullerene or the fullerene derivative being bonded to each other at least partially via a crosslinking group in the photoelectric conversion layer.
