Abstract
A positive electrode plate includes a front positive electrode active material layer on a front surface of a positive electrode metal foil, and having a positive electrode large tapered portion that extends at an incline from one edge of the front surface of the positive electrode metal foil at a positive electrode large inclination angle. A negative electrode plate includes a front negative electrode active material layer on a front surface of a negative electrode metal foil, and having a negative electrode large tapered portion that extends at an incline from one edge of the front surface of the negative electrode metal foil at a negative electrode large inclination angle. The positive and negative electrode plates are alternately laminated with a separator interposed therebetween such that each of their front surfaces is oriented in the same direction in the rear-to-front directional axis along the thickness of the plates.
