Abstract
A droplet discharge amount measuring method for measuring the amount of droplets of a functional solution discharged from a droplet discharge apparatus, the functional solution containing a solid component and a solvent, includes discharging droplets of the functional solution from the droplet discharge apparatus onto a test surface, drying for allowing the solvent on the test surface to evaporate from the droplets so that solid dots be left and measuring the volume of the solid dots using an imaging technique, wherein in drying, the droplets are condensed as the solvent evaporates therefrom, and thus the resulting solid dots have smaller areas than the parent droplets upon landing on the test surface.
