In a thin-film solid secondary cell 1 in which a positive electrode collector layer 20, a positive electrode active material layer 30, a solid electrolyte layer 40, a negative electrode active material layer 50, and a negative electrode collector layer 20 are arranged on a substrate 10, the positive electrode active material layer 30 is a thin film composed of a metal oxide containing a transition metal and lithium, while the negative electrode active material layer 50 is a thin film composed of a semiconductor, a metal, an alloy, or a metal oxide other than a vanadium oxide, and at least the layers other than the collector layers 20 are amorphous thin films. A substance constituting the solid electrolyte layer 40 is a lithium phosphate (Li 3 P0 4 ) or a lithium phosphate having nitrogen added therein (LIPON). |
