Abstract
Exemplary embodiments of the present invention provide a volume measuring method and a volume measuring device which enable a volume of a minute droplet to be measured easily and precisely, and a droplet discharging device including this, and a manufacturing method of an electro-optic device, and the electro-optic device and electronic equipment. A volume measuring method of exemplary embodiments of the present invention include acquiring a central point in horizontal plane view of a droplet dropped on a horizontal plane as origin coordinates by image recognizing device, measuring outline coordinates of a droplet surface with respect to the origin coordinates at plurality of positions while scanning a line segment connecting the acquired central point in horizontal plane view and one arbitrary point A of an outer periphery of the droplet in a radial direction of the droplet by electromagnetic device, and calculating a volume of the droplet based on the measurement result of the outline coordinates.
