Abstract
An all solid battery includes a solid electrolyte layer, a positive electrode layer that includes a positive electrode active material and a negative electrode active material, and a negative electrode layer that includes a positive electrode active material and a negative electrode active material, wherein a relationship “SCathode>SAnode” is satisfied, when a ratio of the positive electrode active material of the positive electrode layer is a ratio A1, a ratio of the negative electrode active material of the positive electrode layer is a ratio B1, a ratio of the positive electrode active material of the negative electrode layer is a ratio A2, a ratio of the negative electrode active material of the negative electrode layer is a ratio B2, SCathode is A1/(A1+B1), and SAnode is A2/(A2+B2).
