Abstract
A liquid discharge head records by generating thermal energy to discharge ink from a discharge port onto a recording medium. The head is provided with a heat dissipating substrate positioned substantially parallel and adjacent to a discharge portion substrate, and a space, which communicates with the outside air, positioned at a surface of the heat dissipating substrate which is opposite the surface of the heat dissipating substrate facing the discharge portion substrate. The space extends in the scanning direction so as to facilitate air flow through the head during carriage movement in order to dissipate heat generated by the head during recording. A cooling fan may be provided to increase the air flow and the consequent heat dissipation.
