Abstract
An all solid battery includes a solid electrolyte layer, and an electrode layer that is provided on each of main faces of the solid electrolyte layer and includes an electrode active material and a conductive auxiliary agent. In a frequency distribution of grain size of the conductive auxiliary agent in a cross section of the electrode layer, two largest peaks, a first peak and a second peak, appear in a range of 5 nm or more and 130 nm or less. In a cumulative distribution of the grain size, a portion appears between the first peak and the second peak where a slope is 0.7 or less (%/nm).
