Abstract
A good-quality slit separator having a small amount of fuzziness at a slit part thereof is to be obtained. The present invention includes: a step (S) of conveying an original sheet (S); and a step (S) of slitting the original sheet (S) by causing a plurality of slitting blades () to cut into the original sheet (S) such that tangent plane angles (θ) in a tangent plane, on which a slitting position is in contact with the original sheet (S), are substantially identical with each other.
