An object of the present invention is to provide a binder for a secondary battery electrode with good uniformity of application of an electrode composition to a current collector. [Solution] A binder for a secondary battery electrode, the binder comprising 10 to 60% by weight of an aliphatic conjugated diene monomer, 0.1 to 10% by weight of an ethylenically unsaturated carboxylic acid monomer, and A copolymer latex obtained by emulsion polymerization of a monomer composed of 30 to 89.9% by weight of another polymerizable monomer, based on a solid content of 100% by weight of the copolymer latex A battery electrode binder comprising a copolymer latex having a filtration residue remaining on a 400 mesh sieve of 0.01% by weight or less. [Selection figure] None |
