The porous coating layer includes a binder polymer and inorganic particles. The separator has a central portion and two end portions. The thickness of the separator at the two end portions in the transverse direction (TD) is larger than the thickness of the separator at the central portion in the TD. The separator prevents generation of a deficiency in adhesion at the two end portions in the TD upon the adhesion of the separator with the electrodes and has uniform adhesion by controlling the thickness of the two end portions of the separator in the TD.
