SOLID-STATE BATTERY AND METHOD FOR PRODUCING SAME

The present application provides a solid-state battery that eliminates the need for additional components such as conductive resin layers, makes it possible to enhance cycle characteristics, and can also be applied to solid-state batteries in which oxide-based solid electrolytes are used. The present application also provides a method for producing the solid-state battery. The present invention is intended to solve the problems described above and relates to a solid-state battery including a positive electrode layer, a negative electrode layer, and a solid electrolyte layer arranged between the positive electrode layer and the negative electrode layer, in which the ratio (negative electrode capacity/positive electrode capacity) of the charge storage capacity of the negative electrode layer to the charge storage capacity of the positive electrode layer is 0.74-0.96.
