PROBLEM TO BE SOLVED: To provide a method for manufacturing a graphite paste capable of suppressing variations in actual viscosity small and manufacturing a graphite paste with uniform properties, even if an actual solid content ratio in the first mixed and kneaded paste at the time of first mixing and kneading is out of an intended value.SOLUTION: A method for manufacturing graphite paste 31Y including graphite particles 32, carboxymethyl cellulose 33 and water AQ comprises: the measurement step S1 of measuring the amount M of basic functional groups BF present on the surfaces of the graphite particles; the first mixing and kneading step S5 of mixing and kneading the graphite particles having the measured amount M of 50.0 mmol/g or more, together with carboxymethyl cellulose and water to prepare a first kneaded paste 31X arranged so that the weight percentage of the graphite particles to the total weight of the graphite particles and the carboxymethyl cellulose falls within a range of 99.0-99.5%; and the dilution, mixing and kneading step S6 of diluting the first kneaded paste with water, and mixing and kneading the diluted paste. |
