Abstract
A recording head includes a stacked body including: a liquid flow path; a plurality of plates stacked on each other; and two communicating holes. Each of the plurality of plates includes: a cross-sectional portion of the liquid flow path; a positioning hole; and a reference hole. Locations of the positioning hole and the reference hole of a plate of the plurality of plates correspond to locations of the reference hole and the positioning hole, respectively, of a plate adjacent to the one plate such that, when the plates are stacked, the positioning holes and the reference holes of adjacent plates alternate to communicate with each other so as to form the two communicating holes, the diameters of the positioning holes of the plurality of plates being successively smaller in order from one side to another side of the stacked body relative to a stack direction of the plurality of plates.
