PROBLEM TO BE SOLVED: To provide a method for easily automatically inserting a film into an automatic winding machine and for securely preventing short-circuit between electrodes in a connection part. SOLUTION: A protection film is arranged in a drawing tab and a surface of a collector at a periphery of the tab. A plurality of through holes are made in the collector. The protection film is fused or stuck to the through holes so as to fix it. Thus, the film can automatically be wound, and high speed winding is easily realized. COPYRIGHT: (C)2008,JPO&INPIT
