Abstract: A dip-molding composition of the present invention contains a latex (A) of a nitrile-group-containing highly saturated copolymer rubber (a). The nitrile-group-containing highly saturated copolymer rubber (a) contains an α,β-ethylenically unsaturated nitrile monomer unit and a conjugated diene monomer unit, and being obtained by hydrogenating at least part of the conjugated diene monomer unit. A dip-molded article of the present invention is produced by dip molding of the above dip-molding composition.
