PROBLEM TO BE SOLVED: To enhance photoelectric transfer efficiency by including semiconductor fine particles sensitized with a coloring matter having specific structure. SOLUTION: A sensitized coloring matter is represented by the formula. In the formula, M1, M2 each represents a metal atom, and Za, Zb, Zc each represents a non-metal atom group forming a ring together with four nitrogen atoms. R1-R3 represent each a carboxy group, a sulfonic group, a hydroxy group, a hydroxamic acid group, a phosphoryl group, a phosphonyl group, or a substituting group substituted with them, a1-a3 each represents an integer of 1-8 but at least one of a1-a3 represents an integer of 1 or more, R1-R3 may be substituted in either position of a ring formed with nitrogen and Za, Zb, and Zc, (b) represents an integer of 0-10, W1 represents a counter ion needed when the counter ion is necessary to neutralize a charge. When (b) is two or more, rings formed by each M2 and Zb may be the same or different. |
