A photoelectric conversion element includes, in this order: a first electrode that includes a photosensitive layer containing a light absorbing agent on a conductive support; a compound layer that contains a surface treating agent and is provided on a surface of the photosensitive layer; and a second electrode, in which the light absorbing agent contains a compound having a perovskite-type crystal structure that has a cation of an element of Group 1 in the periodic table or a cationic organic group A, a cation of a metal atom M other than elements of Group 1 in the periodic table, and an anion of an anionic atom or atomic group X, and the surface treating agent is represented by a specific formula.
