Position detection device and position detection method

Abstract

The present invention provides a position detection device and a position detection method, which, even if a separator or an electrode is deformed, are capable of correcting such deformation and detecting a position of the separator or the electrode with high precision, and are capable of enhancing precision in subsequent steps. The position detection device (200) includes: a pressing unit (240) that presses a sheet member (22), which is cut out from a sheet material (D) wound up in a roll shape and composes a battery element, against a flat reference surface (215); and a position detection unit (230) that detects a position of the sheet member (22) pressed against the reference surface (215) by the pressing unit (240). Then, the position of the sheet member (22), which is detected by the position detection unit (230), is used as position information of the sheet member (22) in a subsequent step.
