A droplet ejection head includes head members, dummy members, a sealant, and elastic members. Each of the head members has a nozzle face where a plurality of nozzles for ejecting droplets are formed and an attaching face which is a back side face with respect to the nozzle face. Each of the dummy members has a dummy nozzle face and an attaching face which is a back side face with respect to the dummy nozzle face. The dummy members are placed at both end sides of the elongated substrate in the longitudinal direction so that second gaps between the outmost head members and the dummy members are formed. The sealant is filled in each of first gaps between the head members and the second gaps, bonds the head members and the dummy members with the outmost head members, and seals the first gaps and the second gaps.
