Separator for battery, laminated separator, lithium ion secondary battery, and battery pack

Provided is a separator for a battery in which, when a ratio of a total length of line segments (Sa), in which an arbitrary straight line (La) intersects with resin fibers (4), to a total length of the straight line (La) on a cross-section of the separator in a thickness direction (TD) is represente...
