<p>A droplet applicator (1) comprises a carrying stage (11) that holds a substrate (50) and is reciprocally movable along a second direction as a substrate carrying direction and a plurality of beams (12) that are provided almost in parallel with a first direction orthogonal to the second direction. Each beam (12) has a plurality of droplet ejection units (2) facing the surface of the substrate (50). Each droplet ejection unit (2) can be moved independently by a slider mechanism (20) along the first direction within a movable area.</p>
