摘要

A liquid droplet ejection head has a liquid introduction part, a pump part which is in communication with the liquid introduction part, and a nozzle forming plate in which a nozzle port is formed in an overlapped manner with the pump part. The nozzle forming plate is formed substantially into a rectangle as seen from a liquid ejection side. A resin is molded in at least one of side surface portions along at least long sides of the nozzle forming plate.
