摘要

PROBLEM TO BE SOLVED: To provide a spray pattern measuring method that enables the accurate detection of the presence or absence of deviation of a spray pattern of a functional membrane on a substrate.SOLUTION: A spray pattern measuring apparatus includes an operation part that determines right and left edges of a spray pattern with respect to a central position corresponding to a position of a droplet discharge head 12 on a spray object substrate 2, from image data on the spray pattern and that determines spray pattern deviation by comparing distances from the central position to the first and second edges, and a determination part that determines whether or not the deviation falls within an allowable range.
