PROBLEM TO BE SOLVED: To provide a nonwoven fabric having high hydrophilicity and liquid retention and high durability, a method for producing the same, a separator using the nonwoven fabric and exhibiting high electrolyte retention, and a long-life alkaline secondary battery. Provide batteries. SOLUTION: By providing a porous layer on the surface of a fiber, an electrolytic solution is retained on the surface and inside of the porous layer, and a separator having a high electrolytic solution retaining property can be obtained. Furthermore, by fixing the porous layer using an adhesive, the durability of the separator is improved. |
