摘要

The present invention employs non-woven fabrics of an olefin resin comprising first filaments having diameters in a range of 3 to 10 mum as a main component and second filaments having diameters in a range of 20 to 40 mum contained at {fraction (1/200)} to {fraction (1/10)} of the whole filaments, as separators for separating positive electrodes from negative electrodes. The first filaments are formed by splitting the second filaments.
