Provided is a support of an electrode active material for a lead acid battery which is excellent in mechanical properties, workability, productivity, hydrophilicity and shape stability, does not use 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 and where a hydrophilic resin is impregnated. Preferably the synthetic fiber fabric is a textile or knitted product and has a porosity of 80-98 %; and the hydrophilic resin is a poly(vinyl alcohol), a water-soluble acrylic resin, a water-soluble polybutadiene resin, a water-soluble vinyl acetic acid resin, a water-soluble vinyl acetate, a water-soluble polyurethane resin or their mixture. |
