To chiefly provide an all-solid battery arranged so that a short circuit owing to dew condensation water can be suppressed.SOLUTION: An all-solid battery is provided according to the present disclosure, which comprises a battery element having a positive electrode, a solid electrolyte layer and a negative electrode in this order and an outer packaging body covering the battery element. The all-solid battery further comprises positive and negative electrode terminals connected to the battery element and disposed so as to protrude from the outer packaging body. The all-solid battery has a concave portion on the side closer to the positive and negative electrode terminals than the battery element in plan view and in an inside region with respect to an outer width of the positive and negative electrode terminals in an outer surface of the outer packaging body, or a convex portion on the side closer to the positive and negative electrode terminals than the battery element in plan view and in a region of an inner width of the positive and electrode terminals in the outer surface of the outer packaging body.SELECTED DRAWING: Figure 1 【課題】本開示は、結露水による短絡が抑制された全固体電池を提供することを主目的とする。【解決手段】本開示においては、正極、固体電解質層および負極をこの順で有する電池要素を外装体で被覆した全固体電池であって、上記電池要素に接続され、上記外装体から突出して配置された正極端子および負極端子をさらに備え、上記外装体外表面において、平面視上で上記電池要素よりも上記正極端子および上記負極端子側であって、かつ、上記正極端子および上記負極端子の外幅よりも内側の領域に凹部を有するか、または、上記外装体外表面において、平面視上で上記電池要素よりも上記正極端子および上記負極端子側であって、かつ、上記正極端子および上記負極端子の内幅の領域に凸部を有する、全固体電池を提供する。【選択図】図１
