1. A manufacturing method for manufacturing an all-solid-state battery in which a current collection foil and an active material layer are stacked, the manufacturing method comprising:
a current collection foil attachment step of attaching the current collection foil to a foil attachment surface of a press roller that includes the foil attachment surface, which is a cylindrical surface, and that is configured to rotate using a central axis of the cylindrical surface as a rotational axis, wherein the press roller includes a plurality of ventilation holes that extend from the foil attachment surface to an interior, and the current collection foil is attached to the foil attachment surface due to a gas being suctioned from the ventilation holes to the interior;
an adhesive provision step of providing an adhesive on the current collection foil attached to the foil attachment surface; and
a pressing step of rotating and moving the current collection foil attached to the foil attachment surface to a surface of the active material layer being transported by a transport apparatus by rotating the press roller, and pressing the current collection foil and the active material layer in a thickness direction between the press roller and the transport apparatus.
