Abstract: A liquid agent application apparatus includes an application nozzle that is movable up and down and in a horizontal plane direction with respect to a board, an application valve that switch between a first state in which supply of a liquid agent to the application nozzle is performed and a second state in which the supply of the liquid agent to the application nozzle is stopped, and a control device that controls these. The control device performs control such that the application nozzle is lowered, the application valve is switched to the second state by standing by a predetermined time after switching the application valve to the first state at a predetermined supply start timing, and the application nozzle is raised after a timing at which a tip end of the application nozzle reaches a lowering end and the application valve is switched to the second state.
