摘要：
A liquid droplet ejection head includes: a nozzle plate that has a plurality of nozzles ejecting a liquid droplet; a flow path member that includes: pressure generating chambers that communicate with the nozzles; and liquid supply paths through which liquid is supplied to the pressure generating chambers; and a damper portion that is disposed in at least one part of a region, the region being on the nozzle plate, corresponding to the liquid supply paths, the damper portion reducing a fluctuation of an ejection amount of the liquid droplets to enable stable ejection.
