PROBLEM TO BE SOLVED: To provide a separator for a clad-type sealed lead acid battery, having improved adhesiveness with respect to a clad-type pole plate and superior electrolyte sustainment and gas permeability. SOLUTION: This separator for the clad-type sealed lead acid battery, using a clad type pole plate for a positive electrode, is formed of an acidproof nonwoven cloth having the ratio of the thickness under pressure at 19.6 kPa (20 kgf/100 cm2) to thickness under pressure at 49 kPa (50 kgf/100 cm2) being 0.7 or smaller.
