Abstract: The present invention provides an entire solid lithium secondary battery comprising: a cathode; an anode; and a solid electrolyte layer interposed between the cathode and the anode. The solid electrolyte layer is formed of a Li(1-x)NbO3 crystal (where 0.10≦x≦0.35) having a trigonal ilmenite crystal structure. This entire solid lithium secondary battery has a high charge-discharge property.
