    摘要: A cell suspension treatment apparatus has a circulation circuit and a filling liquid supply source that supplies a filling liquid to the circulation circuit. The circulation circuit includes a hollow fiber membrane filter, a reservoir, a pump that is provided on a downstream side of the reservoir and on an upstream side of the hollow fiber membrane filter, and a valve that is provided on the downstream side of the reservoir and on an upstream side of the pump. The filling liquid supply source is connected to a portion of the circulation circuit between the first valve and the pump. After the concentrated cell suspension is stored in the reservoir, in a state where the valve is closed and the pump is driven, the filling liquid supply source starts supplying the filling liquid to the circulation circuit to push the cell suspension, which remains in a portion of the circulation circuit from the pump to the inlet port of the reservoir, to flow toward the reservoir by the filling liquid.
