PURPOSE: To provide an assembly device and an assembly method of a head unit by which a plurality of droplet discharge heads can be built into a single carriage stably and with high level of accuracy. CONSTITUTION: The assembly device and method are provided with a recognition means 215 to recognize positions of the carriage 2 and each droplet discharge head 3 as images, a moving means 211 to move the carriage 2, a correction means 212 to slightly move a head holding member 4, a fixing means 213 to fix each head holding member 4 to the carriage, and a control means 215. The control means 215 locates each droplet discharge head 3 against the carriage 2 after fixing the location of the carriage 2 based on the result of recognition by the recognition means 214 and furthermore, fixes each head holding member 4 to the carriage 2.
