Beschreibung
Zusammenfassung:	An all-solid secondary battery includes a cathode layer, an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer. The cathode layer includes a cathode active material layer and a flame-retardant inactive member located on and in contact with the solid electrolyte layer and has a rectangular enclosure shape surrounding side surfaces of the cathode active material layer, wherein the flame-retardant inactive member includes a pair of first side portions and a pair of second side portions connected to the first side portions, the first side portions having uncoated portion corresponding portions corresponding to a cathode uncoated portion of a cathode current collector and an anode uncoated portion of an anode current collector, respectively, and wherein a width of the uncoated portion corresponding portion of the first side portion is greater than a width of the remaining portion of the first side portion.
