Provided is a support of an electrode active material for a lead acid battery which is excellent in mechanical properties, workability and productivity, is free from a glass fiber and shows a good electrolyte permeation. The support(5) of an electrode active material comprises a synthetic fiber fabric which contains 10 wt% or more of a micro-filament yarn having an average diameter of 0.1-10 micrometers and has a micropore. Preferably the synthetic fiber fabric is a textile or knitted product and has a porosity of 80-98 %. Preferably the support of an electrode active material has a thickness of 0.1-0.4 mm, a tensile strength to transverse direction and longitudinal direction of 5 kgf or more and a solution absorption amount per unit volume of 1 g/cc or more. |
