ALL-SOLID-STATE BATTERY

Provided is an all-solid-state battery which is configured to suppress an increase in the resistance of the all-solid-state battery and which is configured to suppress the peeling-off of the solid electrolyte layer. Disclosed is an all-solid-state battery comprising: a cathode comprising a cathode layer, an anode comprising an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer, wherein a width of the cathode layer is smaller than a width of the anode layer and a width of the solid electrolyte layer; wherein the solid electrolyte layer comprises a non-facing portion where the solid electrolyte layer does not face the cathode layer and a facing portion where the solid electrolyte layer faces the cathode layer; and wherein a binder content of the non-facing portion is larger than a binder content of the facing portion.
