An electrode assembly is made by winding a positive electrode, a separator, and a negative electrode, in which the negative electrode includes a negative electrode active material portion made by applying a negative electrode active material onto a negative electrode current collector, a central negative electrode non-coated portion positioned at a winding center portion and having no negative electrode active material, and a negative electrode non-coated portion including an outermost peripheral negative electrode non-coated portion positioned at an outermost winding periphery, in which a variable unit is provided on the outermost peripheral negative electrode non-coated portion and configured to adjust a length or width thereof, and in which the variable unit includes one or more cutout portions having a non-straight shape, and a variable portion configured to adjust a length or width thereof.
