Provided is a method for manufacturing an electrode for an all-solid-state battery comprising steps of applying granules containing an active material on a current collector, aligning and fixing the granules applied on the current collector, applying a solid electrolyte solution on fixed granules, and moving the solid electrolyte solution applied on the granules into pores between the granules. According to one embodiment of the present invention, the step of moving the solid electrolyte solution described above is performed by reducing the pressure by vacuum at 20°C to 40°C. According to the above manufacturing method, the solid electrolyte solution can be effectively and uniformly injected into the pores in the granule layer.
