Liquid jet recorder.

摘要

A liquid jet recording head comprising a first substrate (100) provided with an energy-generating element that generates an energy for discharging a recording liquid, a second substrate (400) jointed to the first substrate, the second substrate having grooves (411,412) that form passages for the recording liquid in accordance to the position of the energy-generating element at the jointing and being integrated with a discharge port-forming member that forming discharge ports (421,422) for the recording liquid on the front side of the grooves, and a force-endowing (500) member that tightly boxes the first and second substrates to each other by a mechanically endowed force has a high reliability and can be produced in a high productivity at a low cost with a smaller number of production steps.
