PROBLEM TO BE SOLVED: To provide a transition metal complex which exhibits strong absorptions in a wide range of spectra and serves as a novel photosensitizer dye having excellent durability, as well as an oxide semiconductor electrode and a dye-sensitized solar cell that contain the dye. SOLUTION: The bivalent transition metal including (i) a bipyridyl polyacidic ligand such as a dicarboxybipyridyl (dcbpy) ligand as an adsorption site for adsorption onto the surface of titanium dioxide particles, (ii) a ligand which is selected from among isothiocyanato, isocyanato, and isoselenato groups and enables absorption excitation/charge transfer at long wavelengths, and (iii) a bipyridyl (bpy) ligand directly bonded to or conjugated to a five-membered heterocyclic ring having an alkyl, an alkoxyalkyl, or an alkoxy group including a quaternary carbon atom which may be optionally substituted by one or more fluoro groups for providing nucleophilic reagent stability to a sensitizer dye to improve the absorbance and bathochromic effect in absorption of the transition metal complex, and the photosensitizer dye having the structure are provided.
