Abstract
Provided is a method for producing an electrode paste capable of readily and reliably removing bubbles from the produced electrode paste. A method includes a step for performing vacuum-defoaming of bubbles present in an electrode paste (8) by vacuuming the inside of a defoaming tank (6) while introducing the electrode paste (8) to the defoaming tank (6). In the step for performing vacuum-defoaming of bubbles present in an electrode paste (8), a rising velocity (fluid surface rising velocity VL) of the fluid surface of the electrode paste (8) in the defoaming tank (6) is made smaller than a rising velocity (reference bubble rising velocity VGa) of the bubbles in the electrode paste (8) by adjusting a flow rate (supply flow rate Q) of the electrode paste (8) introduced to the defoaming tank (6).
