ABSTRACT:
An electricity-heat converter is provided on a substrate for a recording head. The recording head generates heat energy for discharging recording liquid by causing the state change of the liquid to occur. A multi-layer wiring is sandwiched between insulating layers comprising an organic material and is connected electrically to the electricity-heat converter through at least one contact portion formed through the insulating layer. The contact portion is provided in a discharging portion of the recording heads.
