<P>PROBLEM TO BE SOLVED: To suppress generation of burrs and flash on a cut surface. <P>SOLUTION: An electrode cutting device 50 is a device to cut an electrode 23 which includes a collector 14 and an electrode layer 22 formed on the collector 14. The electrode cutting device 50 comprises: a roller 52 to press the electrode; and a cutting blade 53 which is formed on a surface of the roller 52 in a circumferential direction and cuts the electrode 23 when the electrode is pressed by the roller 52. Since the device can cut the electrode 23 while pressing it, burrs and flash on a cut surface of the electrode 23 can be suppressed at the time of cutting. <P>COPYRIGHT: (C)2012,JPO&INPIT |
