Beschreibung
Zusammenfassung:	Provided is a microporous membrane that is suitable for a battery separator, and has good low-temperature characteristics of a battery. The microporous membrane that is suitable for the battery separator, and has good low-temperature characteristics of the battery can be provided by forming the microporous membrane formed of a thermoplastic resin, in which ion resistance is 0.20 or less, reaction resistance is 0.45 or less and total resistance is 0.60 or less.
