ABSTRACT:
A recording head is equipped with a plurality of liquid discharge portions, each having a discharge opening for discharging ink, and a substrate. The substrate is provided with a plurality of electrothermal transducers for generating thermal energy to be utilized for discharging the ink supplied to the liquid discharging portions and a plurality of functional devices connected electrically to the electrothermal transducers. The plurality of functional devices are arranged in a direction diagonal relative to an arrangement direction of the plurality of electrothermal transducers within a region provided with a wiring portion and have different characteristic curves of saturated voltage versus temperature corresponding to the distance from the electrothermal transducers. The region includes common electrode wiring and selective electrode wiring for the plurality of electrothermal transducers and the plurality of functional devices. The plurality of electrothermal transducers are connected to the common electrode wiring. The wiring portion is formed essentially at a layer lower than the layer where the electrothermal transducers are formed.
