Abstract
In the electrode assembly, the first uncoated portion provided at a long side end of a first electrode includes a segment region divided into a plurality of independently bendable segments by a plurality of cut grooves provided along a winding direction. The segment region includes a plurality of segment groups disposed with a group separation pitch along the winding direction. The plurality of segment groups constitute at least one segment alignment on one side of the electrode assembly. At least some of central points of winding turn arcs where the p number of segment groups are located are not located on a predetermined alignment line extending in the radial direction from the center of the core.
