Pasting paper for lead storage battery

[Problem] To provide a paste paper for a lead-acid battery, the paste paper comprising a non-woven fabric using at least three types of fibers as constituent materials. The present invention relates to a paste paper for a lead storage battery, the paste paper having a function of preventing an active material from falling off during battery assembly in the lead storage battery, and preventing layering of an electrolyte caused by charging and discharging of the lead storage battery and degradation of battery performance caused by a change in the size of the active material along with repetition of battery circulation. The purpose of the present invention is to suppress a decrease in charge acceptance of a lead storage battery by reducing the internal resistance value of the lead storage battery while maintaining the prevention of active material shedding and the prevention of layering of an electrolyte solution. [Technical means] Paperboard for lead storage batteries, which is configured from a non-woven fabri
