Provided is a copolymer latex that does not dissipate a substance causing indoor air pollution (sick house) and exhibits excellent long-term storage stability. A monomer comprising 50 to 80 parts by weight of an aliphatic conjugated diene monomer, 20 to 50 parts by weight of a vinyl cyanide monomer, and 0 to 10 parts by weight of an ethylenically unsaturated carboxylic acid monomer. A copolymer latex obtained by emulsion polymerization of a polymer, and 0.001 part of a benzoisothiazoline compound represented by the following general formula (1) with respect to 100 parts by weight (in terms of solid content) of the copolymer latex A copolymer latex containing at least 0.001 part by weight and at least 0.001 part by weight of 2-methyl-4-isothiazolin-3-one and having a redox potential of -100 mV to +300 mV.
