An application device comprises a liquid tank for retaining a liquid, and a discharge unit to which the liquid is supplied from the liquid tank, and which discharges the liquid to an application-target area of an object at a set application width, The discharge unit comprises a head cylinder filled with the liquid supplied from the liquid tank, and the nozzle plate which is provided at one end of the head cylinder in a replaceable manner and which is provided with plural nozzle holes discharging the liquid. The application width can be changed by merely replacing the nozzle plate without changing of an application condition.
