PROBLEM TO BE SOLVED: To obtain a copolymer latex for dip molding, providing a dip-molded product having uniform film thickness, a few pin holes, excellent tensile strength and elongation. SOLUTION: The copolymer latex for dip molding is obtained by subjecting monomers (100 parts wt. of the total of monomers) composed of 50-80 wt.% of 1,3-butadiene, 15-50 wt.% of acrylonitrile, 0-10 wt.% of an ethylenically unsaturated carboxylic acid-based monomer and 0-35 wt.% of an ethylenically unsaturated monomer copolymerizable with the monomers to emulsion polymerization and has 50-65mNm<SP>-1</SP>dynamic surface tension in the case of 10ms surface lifetime.
