Abstract
There is provided a recording head unit that includes a recording head main body that drives a piezoelectric element to generate a pressure change in ink filling a pressure generation chamber so as to eject the ink through a nozzle formed in a nozzle plate; a holder to hold the recording head main body; and a fixing plate to which end surfaces, on the nozzle plate side, of the recording head main body and the holder are fixed. In the stated recording head unit, the fixing plate includes a slope section that is arranged in part of a predetermined region of the fixing plate where neither the holder nor the recording head main body is fixed, and that has a free movement portion of which cross section is formed in a mountain-like shape and which is capable of freely moving in a direction intersecting with a surface direction of the fixing plate; the fixing plate further includes a fixing portion with which a base end of the free movement portion is fixed to the holder; and the fixing plate is so configured as to be expanded/contracted in the surface direction of the fixing plate by a force applied in this direction.
