    摘要： A separator of the present invention for a nonaqueous electrolyte secondary battery is obtained by fluorinating a polyolefin based resin. A contact angle of the separator with a nonaqueous solvent electrolyte is 40° or less a shutdown temperature of the separator is 170°C or less. Further, a multilayered separator of the present invention for a nonaqueous electrolyte secondary battery includes a plurality of layers, at least one of which is the foregoing separator for a nonaqueous electrolyte secondary battery. These separators for nonaqueous electrolyte secondary battery have both a favorable electrolyte-retaining characteristic and a suitable shutdown performance.
