The purpose of the present invention provides a photoelectric conversion element being able to promote the conversion efficiency. The solution of the present invention is a photoelectric conversion element of pigment sensitization type, in which comprises active electrode 10, relative electrode 20 and electrolyte-containing body 30. In the pigment conversion element, a pigment 14 is carried on the metal oxide semiconductive layer 12 of active electrode 10. The said pigment 14 comprises cyanine pigment containing benzyl and indolenine skeletons. Thereby, the said active electrode 10 could inhibit the crystallization of pigment on the surface of metal oxide semiconductive layer 12.
