Nozzle head and droplet application device

A nozzle head comprising:

• a nozzle plate including a plurality of nozzle holes capable of discharging droplets;
• a piezoelectric element including a plurality of first electrodes and a plurality of second electrodes provided alternately and a piezoelectric part provided between the plurality of first electrodes and the plurality of second electrodes, the piezoelectric element being provided for each of the plurality of nozzle holes;
• an actuator plate provided on opposite side of the nozzle plate from a side to which the plurality of nozzle holes are opened, the actuator plate comprising a support part including a protrusion extending above a main surface of the actuator plate;
• a fixing part being insulative and provided on the protrusion, the fixing part being configured to fix each of a plurality of the piezoelectric elements to the support part;
• and
• a conductive part being conductive and provided in direct contact with a side surface of the protrusion and in direct contact with a side surface of the fixing part, the conductive part being configured to electrically connect each of a plurality of the piezoelectric elements to the support part.
