Abstract

The present invention provides a hydrogenated nitrile rubber that has excellent dispersibility and stability in a conductive material dispersion when manufacturing electrodes for electrochemical elements, excellent peel strength in the electrode and excellent crack suppression of the active material in the electrode after cycle testing, and excellent output characteristics of the electrochemical element. The hydrogenated nitrile rubber of the present invention contains a nitrile group-containing monomer unit and a conjugated diene monomer unit and/or an alkylene structural unit, has a weight average molecular weight (Mw) in the range of 1,000 to 1,000,000 and an iodine value of 100 mg/100 mg or less, contains a phenol-based antiaging agent, has a calcium (Ca) content of 1 to 2500 ppm, a ruthenium (Ru) content of 0.5 to 50 ppm, a palladium (Pd) content of 200 ppm or less, a magnesium (Mg) content of 50 ppm or less, and a sodium (Na) content of 300 ppm or less.
