ALL SOLID BATTERY AND DETECTING METHOD OF END POINT VOLTAGE OF THE SAME

An all solid battery includes an oxide-based solid electrolyte layer, a positive electrode layer that is provided on a first main face of the oxide-based solid electrolyte layer and includes a positive electrode active material, and a negative electrode layer that is provided on a second main face of the oxide-based solid electrolyte layer and includes a negative electrode active material. At least one of the positive electrode active material of the positive electrode layer and the negative electrode active material of the negative electrode layer includes a first electrode active material and a second electrode active material of which average operation potentials (vs Li/Li) are different from each other.
