摘要：
A chloroprene polymer having a structural unit derived from chloroprene and a structural unit derived from an unsaturated nitrile, in which the chloroprene polymer has peak tops at 5.80 to 6.00 ppm and 5.10 to 5.30 ppm in a 1H-NMR spectrum as measured in a deuterochloroform solvent, in the 1H-NMR spectrum, a peak area ratio A/B of a peak area A at 5.80 to 6.00 ppm and a peak area B at 4.05 to 6.20 ppm is 0.9/100 to 1.1/100, and the peak area A, the peak area B, and a peak area C at 5.10 to 5.30 ppm satisfy formula "(C - 2A)B ≤ 2.0/100", and a content of the structural unit derived from an unsaturated nitrile is more than 0% by mass and 23% by mass or less.
