Abstract
A liquid jet recording head comprises a first substrate provided with an energy-generating element that generates an energy for discharging a recording liquid, a second substrate joining to the first substrate, the second substrate having grooves that form passages for the recording liquid in accordance to the position of the energy-generating element at the joining and being integrated with a discharge port-forming member that forms discharge ports for the recording liquid on the front side of the grooves, and a force-endowing member that tightly fixes the first and second substrates to each other by a mechanically endowed force. The head has a high reliability and can be produced in a high productivity at a low cost with a smaller number of production steps.
