description PROBLEM TO BE SOLVED: To provide a porous separator elongated material which satisfies both of the requirements for an adequate electrolyte solution injection property (absorbency) and an adequate electrolyte solution retaining property (liquid retentivity).SOLUTION: A porous separator elongated material 12a', 12b' comprises a right side end portion (first side face) 12c' formed in a trapezoidal shape, and a left side end portion (second side face) 12d' formed in a curved trapezoid-like shape which are opposed to each other in a traverse direction orthogonal to a longitudinal direction thereof, and which are each a cut side face. The first side face is larger, in absorbency, than the second side face.SELECTED DRAWING: Figure 9 【課題】良好な電解液の注入特性（吸液性）と良好な電解液の保持特性（保液性）とを共に満たす多孔質セパレータ長尺を提供する。【解決手段】切断側面であるとともに、長手方向と直交する横断方向において互いに対向する、台形形状に形成された右側端部（第１側面）１２ｃ'と湾曲形状に形成された左側端部（第２側面）１２ｄ'とを備え、第１側面の吸液性が第２側面の吸液性よりも大きい多孔質セパレータ長尺１２ａ'、１２ｂ'。【選択図】図９
