Liquid droplet discharge head

A liquid droplet discharge head comprising:

• a plurality of discharge unit parts, each of the discharge unit parts extends in a first direction and is configured to discharge liquid droplets, wherein the discharge unit parts are arranged in a second direction intersecting with the first direction,
• wherein each of the discharge unit parts comprises:
• a nozzle column configured by a plurality of nozzles arranged in the first direction;
• a liquid droplet discharge surface in which the nozzle column is arranged;
• a common flow path, which comprises a plurality of ink introduction ports for supplying ink to the nozzles, and which extends in the first direction;
• a plurality of pressure chambers, which is arranged between the ink introduction ports and the nozzles, and which is configured to receive a pressure for discharging the ink from the nozzles;
• a damper chamber, which is arranged at a position facing the common flow path, and which extends in the first direction;
• a damper wall, which is arranged between the damper chamber and the common flow path, and which is configured to be bent depending on pressure variation in the common flow path;
• and
• a pillar part which connects the damper wall and a separate wall that is different from the damper wall in the damper chamber,
• wherein a position of the pillar part of at least one discharge unit part of the discharge unit parts in the first direction is deviated from a position of the pillar part in the other discharge unit part.
