<P>PROBLEM TO BE SOLVED: To provide a thin-film solid secondary battery of excellent transparency as a whole while maintaining battery performance. <P>SOLUTION: Of the thin-film solid secondary battery 1 made by laminating a cathode collector layer 20, a cathode active material layer 30, a solid electrolyte layer 40, an anode active material layer 50, and an anode collector layer 20, every layer is composed of a transparent thin film. The cathode active material layer 30 and the anode active material layer 50 consist of matters different from each other selected from lithium-titanium oxide, niobium pentoxide, titanium oxide, indium oxide, zinc oxide, tin oxide, nickel oxide, indium oxide with tin added (ITO), zinc oxide with aluminum added (AZO), zinc oxide with gallium added (GZO), tin oxide with antimony added(ATO), tin oxide with fluorine added (FTO), and nickel oxide with lithium added(NiO-Li). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
