Abstract
A liquid ejection head includes a plurality of nozzle arrays extending along a first direction and through which liquid is ejected towards a second direction perpendicular to the first direction, a plurality of substrates extending along the first and second directions, the substrates corresponding to the nozzle arrays, a plurality of heat generating circuits each disposed on a corresponding one of the substrates, a temperature control structure that contacts the heat generating circuits for controlling temperature thereof, and one or more plate springs each biased to push one or more of the heat generating circuits against the temperature control structure.
