The laser device is also configured to move the laser from one edge of the electrode portion to another edge of the electrode portion to cut and separate a respective electrode sheet including the tab from the original sheet. The laser is configured to cut out the tab from the ear portion and cut and separate the respective electrode sheet including the tab from the original sheet as the conveyor is moving the original sheet.

Laser processing apparatus

A laser processing apparatus includes a feeding mechanism including at least one feeding roller and winds the electrode sheet around an outer circumferential surface of the feeding roller to feed the electrode sheet in a feeding direction. When an imaginary contact plane surface contacted with a first surface of the electrode sheet on the laser processing points generated on the electrode sheet by a laser irradiation mechanism is determined as a boundary, a region on a side where the electrode sheet is contacted with the imaginary contact plane surface is defined as a first region and a region on an opposite side is defined as a second region. A peripheral edge of an opening portion of the dust collection hood is placed in the first region with respect to the imaginary contact plane surface.
