Abstract:
Provided is a separator for an electrochemical element, the separator having improved tensile strength and short-circuit resistance while maintaining the impedance characteristics and denseness expected of a separator comprising highly beaten regenerated cellulose fibers. The separator for an electrochemical element is interposed between a pair of electrodes and capable of holding an electrolytic solution containing an electrolyte, the separator for an electrochemical element comprising: 20 to 80 mass % of natural cellulose fibers A in which the length weighted average fiber length is 0.30 to 1.19 mm and the CSF is 500 to 50 ml; 10 to 50 mass % of natural cellulose fibers B in which the length weighted average fiber length and the maximum distribution fiber length are 1.20 to 1.99 mm and the CSF is 500 to 50 ml; and 10 to 50 mass % of beaten regenerated cellulose fibers.

Claim (Index 2):
The separator for an electrochemical element according to  claim 1 , wherein the natural cellulose fibers A are at least one selected from hardwood pulps, esparto pulps, and straw pulps.
