PROBLEM TO BE SOLVED: To provide a winding device that can enhance a material yield, etc.SOLUTION: A winding device 60 comprises: electrode sheet feeding mechanisms 61 and 62 for feeding electrode sheets 5 and 6; and separator sheet feeding mechanisms 63 and 64 for feeding separator sheets 3 and 4. Respective sheets fed by the respective sheet feeding mechanisms 61 to 64 are wound as a battery element with being overlapped in a winding mechanism 65. A discarded material winding mechanism 80 is provided in the electrode sheet feeding mechanisms 61 and 62. Parts of the electrode sheets 5 and 6 containing defects are wound as discarded material by the discarded material winding mechanism 80. |
