Abstract: front page image
(EN)In a side face (12c) of a separator long body (12a, 12b), the value of the edge length (R)/the long-side length (P) is less than 1.04, and so it is possible to provide a porous separator long body in which the possibility of tearing during operation is inhibited.
(FR)Selon la présente invention, dans une face latérale (12c) d'un long corps de séparateur (12a, 12b), la valeur de la longueur de bord (R)/longueur de côté long (P) est inférieure à 1,04, et ainsi, il est possible de fournir un long corps de séparateur poreux dans lequel la possibilité de déchirement pendant l'utilisation est inhibée.
(JA)セパレータ長尺(12a・12b)の側面(12c)において、エッジ長さ(R)/長辺長さ(P)の値が1.04未満であるので、作業中に、裂けてしまう可能性を抑制させた多孔質セパレータ長尺を提供できる。
