PROBLEM TO BE SOLVED: To easily prevent the occurrence of unevenness in a coating film which is caused by a difference in a droplet discharge amount between the nozzles of a coating head. SOLUTION: A coating device 10 compares average droplet discharge amounts when droplets are discharged in basic discharge patterns from the respective nozzles of a coating head 20 with theoretical average droplet discharge amounts to be discharged in the basic discharge patterns from the nozzles, the patterns concerned composed of the combinations of plural kinds of droplets different in size. When a nozzles's average droplet discharge amount is different from the theoretical average droplet discharge amount thereof, the coating device alters the basic discharge pattern thereof so that the nozzle's average droplet discharge amount may become the theoretical average droplet discharge amount thereof.
