ABSTRACT:
A droplet applying apparatus includes a base11having a mounting surface11aon which a substrate10is to be mounted, beam members41, 42which are fitted to the base11so as to be movable relative to the base11in the arrow A direction, a plurality of droplet ejecting sections6which are fitted to the beam members41, 42so as to be movable in the arrow B direction and which eject droplets to the substrate10mounted on the mounting surface11a, reference members each of which is provided at a site of the beam members41, 42proximate to the ejecting surface of each droplet ejecting section6and whose distance to the mounting surface11ais known, a distance measuring section14for measuring a distance to the ejecting surface of each droplet ejecting section6and a distance to each reference member, and a calculation section15for, based on a distance between the ejecting surface of the one droplet ejecting section6and the distance measuring section14as well as a distance between the one reference member and the distance measuring section14, both measured by the distance measuring section14, plus a known distance between the one reference member and the mounting surface11a, calculating a gap between the ejecting surface of the one droplet ejecting section6and the mounting surface11a.
