Abstract
[Problem] To provide a nonwoven fabric (pasting mat) that does not undergo bonding between the nonwoven fabrics (pasting mats) even under severe conditions (a pressure in winding and a high temperature and a high humidity in transportation, storage, and production). [Means for Resolution] A pasting mat for lead acid batteries, containing a microglass fiber and a heat-fusible binder fiber, wherein the pasting mat has a thickness under a pressure of 20 kPa of 0.02 mm or more and less than 0.1 mm, and has a bonding strength between the pasting mats after being left for 48 hours under a pressure of 5 to 10 kPa in an environment of a temperature of 70 to 90° C. and a humidity of 75% of less than 0.05 N.
