A dye, having a structure represented by formula (1A):
wherein A represents a group of atoms necessary for forming a ring together with the carbon-nitrogen bond; at least one of Y1A and Y2A represents an acidic group, in which when they each represent an acidic group, they may be the same as or different from each other, or when only one of them represents an acidic group, the other represents an electron-withdrawing group; D represents a group to give a dye; n represents an integer of 1 or greater; L represents a single bond or a divalent linking group; and Y3A represents an acidic group.

A method of producing a photoelectric conversion element, which the element contains an electrically conductive support, a photosensitive layer having porous semiconductor fine particles, a charge transfer layer; and a counter electrode;
containing the steps of:
applying a semiconductor fine particle dispersion liquid, in which the content of solids excluding semiconductor fine particles is 10% by mass or less based on the total amount of the dispersion liquid, on the support, to form a coating;
heating the coating, to obtain porous semiconductor fine particles; and
sensitizing the porous particles by adsorption of the following dye:
wherein X represents a group of non-metallic atoms necessary for forming a 7-membered ring; Y represents a dye residue; n represents an integer of 1 or more; Z represents a substituent; m represents 0 or a positive integer; and R
1
represents a hydrogen atom or a specific substituent.
