Abstract
An all solid battery includes a multilayer chip in which each of a plurality of solid electrolyte layers including solid electrolyte and each of a plurality of internal electrodes including an electrode active material are alternately stacked, the multilayer chip having a rectangular parallelepiped shape, the plurality of internal electrodes being alternately exposed to two side faces of the multilayer chip other than two end faces of a stacking direction of the multilayer chip, and a pair of external electrodes that contacts the two side faces. At least one of the pair of external electrodes includes an electrode active material of which a pole is a same as that of an electrode active material of the internal electrode which contacts the one of the pair of external electrodes.
