Beschreibung
Zusammenfassung:	[Problem] To provide a pasting paper that is composed of a nonwoven fabric using at least three types of fibers as constituent materials, and that, in a lead acid battery, has a function to prevent fall-off of an active material in assembling a battery, prevents electrolyte stratification occurring accompanying charging and discharging of the lead acid battery, and moreover inhibits a decrease in the charge acceptability of the lead acid battery by reducing the internal resistance value of the lead acid battery while maintaining prevention of fall-off of the active material and prevention of electrolyte stratification against a decrease in battery performance caused by a change in the size of the active material with repeated battery cycles.[Means for Resolution] A pasting paper for lead acid batteries composed of a nonwoven fabric constituted by at least a glass fiber, an acid-resistant organic fiber, and a non-acid-resistant organic fiber, characterized in that the nonwoven fabric has a wettability of 20 sec/mL or less and a maximum pore size of 70 um or less.
