PROBLEM TO BE SOLVED: To provide an all-solid battery which enables the increase in coulomb efficiency.SOLUTION: An all-solid battery comprises: a negative electrode; a positive electrode; and a solid electrolytic layer disposed between the positive and negative electrodes. The all-solid battery further comprises: a negative electrode current collector; and a positive electrode collector. In the all-solid battery, a metal layer is disposed between the negative electrode and the negative electrode current collector and/or between the positive electrode and the positive electrode collector. In the case of the metal layer making a negative electrode-side metal layer, the negative electrode-side metal layer includes a metal of which the elongation percentage is 22% or more, and a negative electrode-side inactive metal layer arranged by use of a metal which does not electrochemically react with metal ions in an environment of a potential such that a negative electrode active material occludes and releases the metal ions is disposed between the negative electrode-side metal layer and the negative electrode. In the case of the metal layer making a positive electrode-side metal layer, the positive electrode-side metal layer includes a metal of which the elongation percentage is 22% or more, and a positive electrode-side inactive metal layer arranged by use of a metal which does not electrochemically react with metal ions in an environment of a potential such that a positive electrode active material occludes and releases the metal ions is disposed between the positive electrode-side metal layer and the positive electrode. |
