PROBLEM TO BE SOLVED: To enhance a coating width accuracy of electrode active material, and also increase a production efficiency. SOLUTION: This long metal foil collector used in an electrode for a battery, is so composed that pressure-sensitive adhesive tapes having widths in the range of 2 mm or more and 100 mm or less per stripe and having 180-degree exfoliation intensity against aluminum in the range of 5 g/cm or more and 100 g/cm or less, at least to the number of one or more, are arranged in parallel in the lengthy direction. In the manufacture of an electrode for a cell in which the collector is used, an uncoated part necessary for taking out the electrode of the battery can be formed accurately, and efficient electrode production can be executed. |
