1. A method of manufacturing an all-solid-state battery, the method comprising:
forming a first electrode member by forming first active material layers on both surfaces of a first current collector;
pressing the first electrode member to form a pressed first electrode member;
forming a second electrode member by forming second active material layers on both surfaces of a second current collector and forming solid electrolyte layers on the second active material layers, wherein the forming of the second electrode member occurs before any pressing of the second electrode member;
pressing the second electrode member to form a pressed second electrode member;
forming a laminated body by layering the pressed first electrode member and the pressed second electrode member; and
pressing the laminated body by passing the laminated body between a pair of rollers to form a pressed laminated body,
wherein pressing the laminated body comprises applying a pressure so that the pressed laminated body has a thickness of 70 to 80% of a thickness of the laminated body before the pressing.
