A cylindrical battery includes an electrode assembly in which a first electrode, a second electrode, and a separator interposed therebetween are wound. The first electrode and the second electrode include a first uncoated portion and a second uncoated portion, respectively. At least one of the first uncoated portion and the second uncoated portion includes a core-side uncoated portion, an outer circumference uncoated portion, and an intermediate uncoated portion interposed therebetween. At least one of the core-side uncoated portion and the outer circumference uncoated portion has a relatively smaller height than the intermediate uncoated portion in a winding axis direction. The cylindrical battery also includes a battery housing configured to accommodate the electrode assembly through an opening and electrically connected to the second uncoated portion; an external terminal electrically connected to the first uncoated portion through a closed portion of the battery housing; and a cap plate covering the opening.
