Abstract

A positive-electrode belt-shaped sheet is cut while the positive-electrode belt-shaped sheet and a negative-electrode belt-shaped sheet are continuously sent, a cut positive-electrode sheet laminated on the uncut negative-electrode belt-shaped sheet via a separator layer is sent and clamped, the uncut negative-electrode belt-shaped sheet is cut at a cutting gap between the positive-electrode sheets laminated thereon, so as to form a sheet unit including the positive-electrode sheet and the negative-electrode sheet, a lamination shape of the sheet unit is measured so as to determine good or bad of the lamination shape, the sheet unit is classified based on a good/bad determination result, and the sheet units determined as good products is collectively laminated and pressed so as to obtain a laminated electrode body. Here, the positive-electrode belt-shaped sheet is cut while the positive-electrode belt-shaped sheet is clamped.
