摘要： A gravure roll, in which the outside peripheral surface of a metal roll main body has a plurality of oblique line shaped protrusions forming a prescribed angle with the center axis of the roll main body and the coating liquid can be held in a plurality of oblique line shaped recesses formed between each of the plurality of protrusions, is configured such that the roll main body has a diamond-like carbon layer on the entire outer peripheral surface thereof, a head part for each of the plurality of protrusions is cut down, and each of the plurality of protrusions has a trapezoidal cross-sectional shape that becomes gradually narrower in width moving in direction toward the head part. A separator with a uniform weight per unit area can be manufactured wherein the coating liquid is coated onto a base material film using this gravure roll.

摘要： Provided is a multi-layered porous film which includes a functional layer having a controlled thickness in a length-wise direction thereof and which is suitable as a separator for batteries. The multi-layered porous film includes a base film, and a functional layer containing both an inorganic filler and a binder resin, the functional layer being formed on the base film, wherein a difference between a maximum basis weight and a minimum basis weight of the multi-layered porous film in a length-wise direction thereof is equal to or smaller than 2 grams/m2, the basis weight being measured every 100 meters interval. The separator fabricated by cutting a film roll comprised of a multi-layered porous film into pieces each having a given length has small lot-based fluctuation in quality, and makes it possible to fabricate a battery having a small fluctuation in quality.
