The present invention relates to: a method for manufacturing nitrile-based rubber which has a low content of residual emulsifier and exhibits excellent mechanical properties; nitrile-based rubber manufactured thereby; and a rubber composition comprising the nitrile-based rubber. The method for manufacturing nitrile-based rubber comprises a step of polymerizing a monomer mixture including an α,β-unsaturated nitrile-based monomer and a conjugated diene-based monomer in the presence of an emulsifier mixture. 본 발명은 잔류 유화제 함량이 적고, 기계적 물성이 우수한 니트릴계 고무의 제조방법, 이로부터 제조된 니트릴계 고무 및 상기 니트릴계 고무를 포함하는 고무 조성물에 관한 것이다.
