Summary:PROBLEM TO BE SOLVED: To provide a solid battery which can suppress a short circuit owing to a nail pricking without decreasing an energy density.SOLUTION: A solid battery comprises a positive electrode current collector layer, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer and a negative electrode current collector layer in this order. At least one of the positive and negative electrode current collector layers has a breaking strength of 72.7 N/cmor less, which is determined by a sphere flexural test.SELECTED DRAWING: Figure 2 【課題】エネルギー密度を低下させることなく釘刺しによる短絡を抑制することが可能な、固体電池を提供する。【解決手段】正極集電体層、正極活物質層、固体電解質層、負極活物質層、及び、負極集電体層を順に備え、正極集電体層及び負極集電体層の少なくとも何れか一方は、球抗折試験により求められる破断強度が７２．７Ｎ／ｃｍ２以下である、固体電池とする。【選択図】図２
