1. A method of manufacturing an all-solid-state battery electrode, the method comprising:
preparing a mixture comprising a solid-state electrolyte, an active material, and a conductive material;
adding a binder to the mixture so as to be dispersed therein; and
primarily roll-pressing to the mixture in which the binder is dispersed to manufacture a sheet-form electrode as the all-solid-state battery electrode,
wherein the binder included in the sheet-form electrode has a fiber form,
wherein the binder having the fiber form has an average fineness of 20 to 50 nm,
wherein the primarily roll-pressing is performed under a condition in which a press count is 55 to 145,
wherein the primarily roll-pressing is performed under a condition in which a press gap between rolls is 0.8 to 2.0 mm,
wherein the method further comprises:
additionally roll-pressing the sheet-form electrode on which the primarily roll-pressing is performed, under a condition in which a press gap of the additionally roll-pressing is smaller than the press gap of the primarily roll-pressing,
wherein the additionally roll-pressing is performed multiple times.
