<P>PROBLEM TO BE SOLVED: To provide a volume measuring method for an impact dot, which enables acquisition of high-reliability measurement results concerning the volume of an impact dot of a functional liquid drop discharged from each nozzle of a functional-liquid-drop head. Ž<P>SOLUTION: The volume measuring method for an impact dot 10 is employed for measuring the volume of the impact dot 10 impacted on an inspection substrate by using an interferometer 99, by inspection discharge of the functional-liquid-drop discharge head 1. A plurality of kinds of inspection substrates 16 different in water repellence are prepared, and inspection discharge and measurement of the volume of the impact dot 10 are performed by using one inspection substrate 16 determined to accord to a measured humidity of the ambient atmosphere, based on humidity-water repellence data 20 representing the relation between the humidity of an ambient atmosphere and the plurality of kinds of inspection substrates 16 which make the impact dot 10 for measurement be in an appropriate dome shape.
