Zusammenfassung:An electrode position detection device configured to detect a relative positional relationship between a positive electrode (24) and a negative electrode (30) when a packaged electrode (20) and the negative electrode (30) are alternately stacked, the packaged electrode having the positive electrode (24) disposed inside a separator (40) formed in a bag shape. The device includes: a light source (76) configured to project light that penetrates the separator (40) and is reflected by the positive electrode (24) and the negative electrode (30); a camera (84) configured to receive the light reflected by the positive electrode (24) when the packaged positive electrode (20) is positioned on the uppermost layer and to receive the light reflected by the negative electrode (30) when the negative electrode (30) is positioned on the uppermost layer; and a detector (160) configured to detect the relative positional relationship between the positive electrode (24) and the negative electrode (30) based on the results of light reception by the camera (84) when the packaged positive electrode (20) is positioned on the uppermost layer and the results of light reception by the camera (84) when the negative electrode (30) is positioned on the uppermost layer.
