Abstract: Provided is a conductive material paste for a lithium ion secondary battery electrode in which conductive carbon is dispersed well. The conductive material paste for a lithium ion secondary battery electrode contains a dispersant (A), a dispersant (B), conductive carbon, and a solvent. The dispersant (A) is a compound that includes not fewer than 2 and not more than 15 aromatic hydrocarbon monocycles and includes not fewer than 2 and not more than 15 functional groups including either or both of a sulfur atom and a nitrogen atom as averages per one molecule. The dispersant (B) includes an isothiazoline compound.
