Zusammenfassung:	To provide an all-solid-state battery that reduces the precipitation of lithium metal during discharge.SOLUTION: An all-solid-state battery 100 includes a positive electrode layer 11, a solid electrolyte layer 12, and a negative electrode layer 13 containing lithium metal. The all-solid-state battery 100 further includes a low ion conductivity portion 14 arranged around the periphery of the positive electrode layer 11 and having a lower lithium-ion conductivity than the positive electrode layer 11. The low ion conductivity portion 14 overlaps the periphery of the negative electrode layer 13 in plan view.SELECTED DRAWING: Figure 2 【課題】放電時のリチウム金属の析出を低減する全固体電池を提供する。【解決手段】正極層１１と、固体電解質層１２と、リチウム金属を含む負極層１３と、を備える全固体電池１００において、正極層１１の外周を周回するように配置され、正極層１１よりもリチウムイオン伝導率の低い低イオン伝導部１４を備え、低イオン伝導部１４は、平面視で負極層１３の外周と重なっている。【選択図】図２
