Abstract
A droplet ejection head that is attachable to and removable from a droplet ejection apparatus, includes: a nozzle plate having multiple nozzle holes to eject droplets; an individual-channel substrate in which multiple individual-liquid-chambers to supply liquid to the nozzle holes are formed; a common-channel substrate to supply liquid to the individual-channel substrate; a base plate made of metal and including a first positioning part to be engaged with a part of the droplet ejection apparatus at a given position to perform positioning with respect to the droplet ejection apparatus in a direction along an opening surface of the nozzle plate at which the nozzle holes are opened; and a housing made of resin and including a second positioning part to perform positioning with respect to the droplet ejection apparatus in a direction intersecting with the opening surface.
