PROBLEM TO BE SOLVED: To obtain a separator for lithium secondary battery having an excellent ion permeability, and capable of being laminated integrally with an electrode.SOLUTION: 1) A separator for lithium secondary battery in which an ion permeable adhesive layer, composed of a polyolefin resin indicating adhesiveness, is formed on one or both sides of a porous film composed of a polyolefin-based resin. 2) A separator for lithium secondary battery to be used while being laminated integrally with the electrode. Preferably, the polyolefin resin is a polyolefin-based resin exhibiting adhesiveness in thermocompression of 70-120°C. |
