Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an improved titania electrode which is a constituting member of a highly efficient dye-sensitized solar cell. SOLUTION: A porous titania thin film is fabricated by forming a thin film composed of titania particles of which the average primary particle diameter is 100 nm or less on a conductive transparent substrate, and the ion-implanted porous titania thin film electrode material is manufactured, at acceleration voltage of 0.5 to 200 kV by implanting ions containing at least one kind of ion selected from a group composed of oxygen ion, sulfur ion, nitrogen ion, phosphorous ion, carbon ion, silicon ion, fluoride ion, chloride ion, titanium ion, zirconium ion, hafnium ion, vanadium ion, niobium ion, silver ion, tantalum ion, scandium ion, yttrium ion, and lanthanum ion into the titania thin film, and making the ion constituting element contained in the titania particles.
