Abstract
A cell electrode plate in which at least one of opposite widthwise ends of longitudinally discontinuous exposed portions with no coatings made of electrode active material on a core member made of metal foil includes pass-by transition portions for press rolls, the transition portions having a thickness substantially the same as that of the coatings. As a result, without complicating a production line, a core member is prevented from being broken and the production line is operated smoothly so as to attain improved productive efficiency and reduced equipment expenses.
