Zusammenfassung:	To provide a method for producing a chloroprene polymer latex used for a chloroprene adhesive, offering a highly good balance between initial adhesion and heat resistance.SOLUTION: A method for producing a chloroprene polymer latex includes, in the presence of an emulsifier and a chain transfer agent, subjecting chloroprene to emulsion radical homopolymerization, or subjecting chloroprene and a monomer copolymerizable with the chloroprene to emulsion radical copolymerization. When the monomer content is 100 pts.mass, the content of the emulsifier is 6.0 pts.mass or more and 8.0 pts.mass or less and the content of the chain transfer agent is 0.085 pts.mass or more and 0.100 pts.mass or less, and the polymerization temperature is 0°C or higher and 20°C or lower.SELECTED DRAWING: None 【課題】高次元で初期接着力と耐熱性のバランスに優れたクロロプレン系接着剤に用いるクロロプレン重合体ラテックスの製造方法を提供する。【解決手段】乳化剤及び連鎖移動剤の存在下、クロロプレンを乳化ラジカル単独重合させるか、クロロプレン及び前記クロロプレンと共重合可能なモノマーを乳化ラジカル共重合させることによりクロロプレン重合体ラテックスを製造する方法であって、前記乳化剤の量がモノマーを１００質量部としたときに６．０質量部以上８．０質量部以下であり、前記連鎖移動剤の量がモノマーを１００質量部としたときに０．０８５質量部以上０．１００質量部以下であり、重合温度が０℃以上２０℃以下であることを特徴とする製造方法。【選択図】なし
