To sufficiently restrain cut chips of a collector from being melted on an upper blade side surface at the time of cutting a sheet-typed electrode, and sufficiently restrain generation of burrs at the cut surface of the collector.
A rotating shaft 2 on which one or more upper blades 4 are installed and a rotating shaft 5 to which one or more lower blades 7 are installed are disposed in parallel to each other so that a periphery side surface 4a of the upper blade 4 and a periphery side surface 7a of the lower blade 7 are brought into contact with each other to obtain a prescribed bite depth. The thickness of the upper blade 4 is ≥1 mm, a blade top angle of the upper blade 4 is 75 to 88°, the hardness of the upper blade 4 and the lower blade 7 is ≤6.9×103 to 8.8×103 N/mm2, a gap between the hardness of the upper blade 4 and the hardness of the lower blade 7 is ≤4.9×102 N/mm2, surface roughness of the upper blade 4 and the lower blade 7 is ≤4 μm, and the gap between the surface roughness of the upper blade 4 and the surface roughness of the lower blade 7 is ≤2 μm.
