<p>PROBLEM TO BE SOLVED: To provide a separator for an electrolytic capacitor, and an aluminum electrolytic capacitor which make possible to largely improve the impregnatability with an electrolytic solution, to avoid worsening a short circuit defect rate, and to improve capacitor's impedance property, especially an equivalent series resistance.SOLUTION: A separator for an electrolytic capacitor is to be interposed between an anode foil and a cathode foil. The separator for an electrolytic capacitor has no less than 35 wt.% of pulp blended therein, provided that the pulp includes no less than 94% ofαcellulose. The pulp can be produced by making paper with a fourdrinier-cylinder combination machine, in which any of pulp made up of seed hair fiber, dissolving pulp and mercerized pulp is used as a raw material.</p> |
