A polyethylene microporous membrane which comprises a polyethylene resin containing 1% by mass or more of an ultra-high molecular weight polyethylene having a mass average molecular weight of 7 x 105 or higher and having the ratio of the number average molecular weight to the mass average molecular weight of 5 to 300, and which comprises (a) a coarsely structured layer which is formed on at least one surface and has an average pore size of exceeding 0.04 µm and (b) a densely structured layer having an average pore size of 0.04 µm or less, wherein the area ratio of the densely structured layer to the coarsely structured layer on the cross-section surface of the membrane is 0.1 to 0.8.

La présente invention concerne une membrane microporeuse en polyéthylène qui comprend une résine polyéthylène contenant 1% en masse ou plus d'un polyéthylène à ultra-haut poids moléculaire dont le poids moléculaire moyen en masse est supérieur ou égal à 7 x 105 et dont le rapport du poids moléculaire moyen en nombre et du poids moléculaire moyen en masse est compris entre 5 et 300, et qui comprend (a) une couche grossièrement structurée qui est disposée sur au moins une surface et dont la taille de pores moyenne est supérieure à 0,04 µm et (b) une couche densément structurée dont la taille de pores moyenne est inférieure ou égale à 0,04 µm, le rapport de surface de la couche densément structurée et de la couche grossièrement structurée sur la surface de section transversale de la membrane étant compris entre 0,1 et 0,8.
