ELECTRODE MANUFACTURING DEVICE USED FOR LASER NOTCHING OF ELECTRODE

There is provided an electrode manufacturing device including: a transfer part continuously transferring an electrode sheet in order to perform an electrode notching process; a laser irradiation part irradiating the electrode sheet with a laser beam to perform the electrode notching process; and a pattern jig positioned at a portion facing the laser irradiation part with the electrode sheet interposed therebetween to support the electrode sheet, wherein the pattern jig includes a panel including a pattern hole through which the laser beam that has notched the electrode sheet passes, and the pattern hole has a structure in which it becomes wide from the front toward the rear based on a laser beam traveling direction.
