A highly saturated nitrile rubber composition containing a carboxyl group-containing highly saturated nitrile rubber (A1) which contains ±,²-ethylenically unsaturated nitrile monomer units 15 to 60 wt% and ±,²-ethylenically unsaturated dicarboxylic acid monoester monomer units 1 to 60 wt% and has an iodine value of 120 or less, a highly saturated nitrile rubber (A2) which contains ±,²-ethylenically unsaturated nitrile monomer units 15 to 60 wt%, has a content of the ±,²-ethylenically unsaturated dicarboxylic acid monoester monomer units of 0.9 wt% or less, and has an iodine value of 120 or less, and a polyamide resin (B), a content ratio of the carboxyl group-containing highly saturated nitrile rubber (A1) and the highly saturated nitrile rubber (A2) being a weight ratio of "carboxyl group-containing highly saturated nitrile rubber (A1): highly saturated nitrile rubber (A2)" of 2:98 to 98:2, is provided. |
