Abstract: A manufacturing device for manufacturing an electrode assembly by laminating unit electrode assemblies in each of which an electrode is placed on a separator. The device includes a transferring device that includes a sucking plate and transfers, onto the positional adjustment stage, each of the unit electrode assemblies sucked up by the sucking plate. Moreover, an image capturing device captures an image of the electrode of each of the unit electrode assemblies placed on the positional adjustment stage. A positional adjustment device positionally adjusts the positional adjustment stage based on the image of the electrode captured, and a transferring and laminating device picks up each unit electrode assembly and transfers each to a lamination stage and performs a lamination process. At least part of the sucking plate is transparent and the image capturing device captures an image of the electrode from above the transparent portion of the sucking plate.

Abstract: A method of ink application on a substrate having a plurality of reference marks includes a step of setting a plurality of divided areas on the substrate and measuring positions of the reference marks in each of the divided areas, a step of acquiring a deviation amount of a gravity center of a measured figure defined by the positions of the reference marks, a step of acquiring a corrected applied position by correcting a designed applied position on the basis of the deviation amount of the gravity center, and a step of applying ink onto the substrate according to the corrected applied position.
