Claim 0:
1. An application method of performing linear application onto an application target using an application device, the application device comprising:
a discharge device that is of jet type; and
a relative driving device configured to move the discharge device and the application target relative to each other,
the discharge device comprising:
a nozzle having a plurality of discharge ports;
a liquid chamber communicating with the plurality of discharge ports via a plurality of discharge flow paths; and
a plunger rod that reciprocates in the liquid chamber and is narrower than the liquid chamber,
wherein the nozzle communicates with the liquid chamber and has a truncated-cone-shaped inner space into which the plunger rod proceeds, the truncated-cone-shaped inner space being surrounded and defined by an upper inside surface of a side wall of the nozzle, a tapered surface of the nozzle that narrows downward from the upper inside surface, and an inner bottom surface located at a lower end of the tapered surface,
wherein the inner bottom surface is constituted by a plane perpendicular to an axis of the plunger,
wherein the plurality of discharge flow paths comprises respective inclined inflow ports continuous with the tapered surface of the nozzle and each of the inflow ports is inclined downward toward the center of the nozzle,
wherein the plurality of discharge ports is arranged on a straight nozzle arrangement line, and arranged with such a distance therebetween that globs of a liquid material having landed on the application target join together to form an application line, and
the method includes forming an application line perpendicular to the nozzle arrangement line by, while moving the discharge device and the application target relative to each other in a direction perpendicular to the nozzle arrangement line, successively discharging the liquid material such that a plurality of liquid globs having been discharged from the plurality of discharge ports have no contact with each other before landing on the application target, and letting the globs of the liquid material having landed join together on the application target.
