PROBLEM TO BE SOLVED: To provide a production method and a production apparatus of electrode paste that can exhibit excellent battery performance.SOLUTION: A method of producing electrode paste by using a multi-axis kneading machine in a production apparatus 1 of electrode paste includes a step for feeding powder containing an active material and a first solvent to the multi-axis kneading machine substantially simultaneously, and kneading the powder and the first solvent. When the dropping and feeding speed of powder is A (g/sec), the capability ratio is B, the loose bulk density of powder is C (g/cc), the space volume of the multi-axis kneading machine is D (cc), the spiral laps (rotation) of the screw of multi-axis kneading machine per unit length is E, and the number of revolutions of the rotating shaft of multi-axis kneading machine is F (revolutions/sec), the capability ratio B derived according to the following<formula 1>is 1/8 or less.<formula 1>A÷(C×D×F÷E)=B. |
