PROBLEM TO BE SOLVED: To provide a winder and a winding method of an electrode, capable of suppressing a misalignment of an electrode in a winding axial direction, in an electrode body formed by winding an electrode even when the electrode has a curved portion.SOLUTION: In a winding method of an electrode, a position of an electrode in a transverse direction during conveyance is detected, a position of the electrode in a transverse direction is adjusted on the basis of the detection result, and a conveyance speed of the electrode is increased after a portion including an electrode end part on the outer peripheral side of a roll has been fed out from the roll, the portion having a predetermined length in the electrode.SELECTED DRAWING: Figure 7 |
