Abstract: The occurrence of separation or reaggregation is suppressed in a suspension such as a battery electrode slurry. A battery electrode slurry distributing apparatus includes: a circulation pipe via which a positive electrode slurry is to be circulated; and a control unit that controls the supply of the positive electrode slurry to each of coaters. In a period in which either the coater is allowed to receive the supply of the positive electrode slurry, the control unit inhibits the supply of the positive electrode slurry to the other coater. The circulation pipe is structured in a polygonal loop. The coaters are connected to respective elbow portions formed in the circulation pipe via the pipes, respectively.
