A method for producing a separator, comprising a removing step of causing a removing section to remove both end parts of a base film, which is transferred by being given a tension, in a width direction of the base film, the width direction being a direction which is (i) substantially perpendicular to a transferring direction of the base film and (ii) substantially parallel to a surface of the base film, the removing section including:
- a first cutting section for cutting off one of the both end parts of the base film;
- a second cutting section for cutting off the other one of the both end parts of the base film;
- and
- a fixing shaft that extends in the width direction of the base film and fixes the first cutting section and the second cutting section.
