    Abstract: A filtration efficiency, which is similar to the filtration efficiency obtained when a plurality of filters are provided, can be obtained by one filter, and decrease in throughput can be prevented. Based on a control signal from a control unit (101), a resist liquid (L) is sucked into a pump (70) through a filter. A part of the resist liquid sucked in the pump is discharged from a discharge nozzle (7). The remaining resist liquid is returned to a supply conduit (51b) on a primary side of the filter. A process is synthesized by adding a replenishment amount equal to the discharge amount to the return amount. The discharge of the synthesized resist liquid and the filtration thereof by the filter are performed the number of times corresponding to a rate between the discharge amount and the return amount.
