Abstract

An electrode assembly has a positive sheet, a negative sheet, and separators that are stacked and wounded. A joint portion is formed by thermally fusion bonding or compression bonding of the separators at one end in a width direction thereof so that one end of the positive sheet on an opposite side in a width direction with respect to a positive lead is wrapped by the separators. Arranged outside of the joint portion in the width direction is a separating portion where the separators are separated from each other. A protecting layer made of an insulating material is formed on the end face of the positive sheet. The positive sheet is reliably prevented from being in contact with a foreign material.
