Abstract
A droplet forming method, for forming a droplet, constituted of a sample liquid, on a substrateby applying a pulse voltage P between the sample liquid, retained in a nozzle, and the substrate, disposed opposite a tip of the nozzle, to discharge the sample liquidfrom the tip of the nozzle, includes: a waveform measuring step Sof measuring a temporal waveform of a current I that flows between the sample liquidin the nozzleand the substrate; and an application condition determining step Sof determining, based on the temporal waveform of the current I, an application condition of the pulse voltage P during the forming of the dropleton the substrate
