This dialysis-fluid supply system, which mixes a diluent and at least two drugs to generate a dialysis fluid, and outputs said dialysis fluid, is provided with: a mixing tank which mixes the drugs and the diluent to generate the dialysis fluid； a storage tank which stores and outputs the dialysis fluid generated by the mixing tank； a transport mechanism for transporting, to the storage tank, the dialysis fluid generated by the mixing tank； an output mechanism for outputting, to a dialysis device, the dialysis fluid stored in the storage tank； and a control unit for controlling the driving of the transport mechanism and the output mechanism.
