ALL SOLID BATTERY AND MANUFACTURING METHOD OF THE SAME

An all solid battery includes a multilayer structure in which solid electrolyte layers and internal electrodes are alternately stacked, the plurality of internal electrodes including an electrode active material and a carbon material, the multilayer structure having a rectangular parallelepiped shape, the plurality of internal electrodes being alternately exposed to two different faces of the multilayer structure, a first cover layer provided on an upper face of the multilayer structure in a stacking direction, and a second cover layer provided on a lower face of the multilayer structure in the stacking direction. Each thickness of the plurality of internal electrodes is equal to or more than each thickness of the plurality of solid electrolyte layers. Vickers hardness of the plurality of solid electrolyte layers and Vickers hardness of the first and second cover layers are larger than Vickers hardness of the plurality of internal electrodes.
