To provide a carbon nanotube dispersion liquid in which carbon nanotubes are uniformly dispersed in a dispersion medium and a method for producing the same and to provide a method for producing an electrode slurry and an electrode using the same.SOLUTION: There is provided a carbon nanotube dispersion liquid which contains bundle-type carbon nanotubes, a dispersion medium and a partially hydrogenated nitrile rubber having a residual double bond (RDB) value of 0.5 to 40 wt.% as calculated by the following mathematical expression 1, in which the dispersed particle diameters of the carbon nanotubes have a particle size distribution Dof 3 to 10 μm. [Mathematical expression 1] RDB (wt.%)=BD wt./(Bd wt.+HBD wt.)×100 (in the mathematical expression 1, BD represents a structural unit derived from a conjugated diene and HBD represents a structural unit derived from a hydrogenated conjugated diene, respectively.)SELECTED DRAWING: None 【課題】カーボンナノチューブが分散媒に均一に分散されたカーボンナノチューブ分散液、その製造方法、およびそれを用いて電極スラリーおよび電極を製造する方法の提供。【解決手段】バンドル型カーボンナノチューブと、分散媒と、下記数学式１によって計算される残留二重結合（ＲＤＢ）値が０．５〜４０重量％である部分水素化ニトリルゴムと、を含み、前記カーボンナノチューブの分散粒径は、粒径分布Ｄ50が３〜１０μｍであることを特徴とする、カーボンナノチューブ分散液。［数学式１］ＲＤＢ（重量％）＝ＢＤ重量／（ＢＤ重量＋ＨＢＤ重量）×１００(前記数学式１において、ＢＤは共役ジエン由来の構造単位を、ＨＢＤは水素化された共役ジエン由来の構造単位をそれぞれ意味する)【選択図】なし
