Abstract
A separator arranged between a pair of electrode sheets includes a nonwoven fabric formed of thermoplastic resin fibers spun by a melt-blowing process. The fibers include fine fibers having fiber diameters of 0.1 μm or more and 1 μm or less, and thick fibers having fiber diameters of 8 μm or more and 30 μm or less. The fine fibers and the thick fibers are mixed over the entire thickness of the nonwoven fabric.
