In a flow coater for applying coating liquid to a plate member such as a printed board by a curtain flow method, a heat exchanger unit of a temperature controller is arranged in a collection tray which is arranged below a coating liquid supplying head across a conveyance path for the plate member. This heat exchanger unit has a coil-shaped structure. The coating liquid is caused to flow down curtainly from the head to come in contact with the heat exchanger unit in which the heat exchange is carried out. Since a small amount of coating liquid comes in contact with the heat exchanger unit, an excellent efficiency of the heat exchange can be obtained, and hence it is possible to cope speedily and accurately with temperature changes. In addition, since after the coating liquid has flowed down from the head, the coating liquid flows naturally down in the tray while contacting the heat exchanger unit, there is no need of providing a special drive apparatus therefor.
