Abstract
Layer cell includes an outer casing, positive electrode, negative electrode, separator disposed between the positive electrode and the negative electrode, and electrically conductive current collector passing through the positive electrode, the negative electrode and the separator in an axial direction of the outer casing. The positive electrode, the negative electrode and the separator are stacked in the axial direction of the outer casing. First electrode which is one of the positive electrode and the negative electrode is in contact with an inner surface of the outer casing, but is not in contact with the current collector. Second electrode which is the other electrode is not in contact with the outer casing, but is in contact with the current collector. An outer edge of the second electrode is covered with the separator. Peripheral edge of a hole, in the first electrode is covered with the separator.
