Claim Text:
1. An electrode paste manufacturing method comprising: evacuating a deaerating tank to which an outlet of a mohno pump is connected, by a vacuum pump, such that a conduit system on the deaerating tank side of an airtight line formed at a contact portion between a rotor and a stator of the mohno pump is a closed system with the airtight line being a boundary, an inlet of the vacuum pump being connected to the deaerating tank, and an inlet of the mohno pump being connected to an outlet of a twin screw extrusion mixer; and continuously vacuum deaerating the electrode paste inside the conduit system on the deaerating tank side of the airtight line and inside the deaerating tank, by transferring the electrode paste to the deaerating tank using the mohno pump, while keeping the conduit system on the deaerating tank side of the airtight line in a vacuum state.
