Claim 10:
11. A discharge device that is of jet type for implementing the application method according to claim 1, 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.
