  "textContent": "A thin separator for electrochemical elements, which has achieved chemical stability, while maintaining a good balance among short-circuit resistance, resistivity, electrolyte solution impregnatability and electrolyte solution retainability of the separator. A separator for electrochemical elements, which is interposed between a pair of electrodes so as to separate the electrodes from each other, and which holds an electrolyte solution. This separator for electrochemical elements is composed of beaten cellulose fibers and thermoplastic synthetic fibers, and has a thickness of 5.0-30.0 μm and a density of 0.50-0.75 g/cm; and the thickness X (μm) and the air resistance Y (second/100 ml) of this separator for electrochemical elements satisfy formula 1: Y≥0.01X−0.6X+11.5.",
