The method comprises a step for preparing a beltlike positive electrode plate whose thickness and width are PT and PW respectively, a beltlike negative electrode plate whose thickness and width are NT and NW respectively, a beltlike first separator whose width is longer than PW+2PT, and a beltlike second separator whose width is longer than NW+2NT; a second step for making a set of the first separator and the positive electrode plate by putting a central part of the first separator and a surface of the positive electrode plate together, and by putting each horizontal end of the first separator and each side surface of the positive electrode plate together; a third step for making a set of the second separator and the negative electrode plate by putting a central part of the second separator and a surface of the negative electrode plate together, and by putting each horizontal end of the second separator and each side surface of the negative electrode plate together; and a fourth step for spirally winding the set of the first separator and the positive electrode plate with the set of the second separator and the negative electrode plate in a longitudinal direction of the positive and the negative electrode plate. |
