A coating apparatus includes an open/close valve having a motor that allows control of opening operation and closing operation in accordance with electric signals applied from a controller. The coating apparatus further includes a suck back valve having a motor that allows control of a volume variation in a flow path for suck back that is in communication with an upstream side and a downstream side of a pipe in accordance with electric signals from the controller. The controller allows control of start of the closing operation of the open/close valve and start of suction operation of the suck back valve through application of the electric signals to the respective motors. This achieves simple adjustment of liquid cut-off.
