PROBLEM TO BE SOLVED: To provide a negative electrode paste or the like, including negative electrode active material particles in a good dispersion state and capable of preventing an increase in battery internal resistance.SOLUTION: A negative electrode paste 70 is a negative electrode paste for a lithium ion secondary battery 100, and obtained by dispersing negative electrode active material particles 10, carboxymethyl cellulose (CMC) 20, and an SBR emulsion 30x including styrene-butadiene rubber (SBR) particles 30 into water 40. In the negative electrode paste 70, the CMC 20 with an amount corresponding to 0.10-0.40 wt.% of the negative electrode active material particles 10 is adsorbed to the negative electrode active material particles 10. |
