A liquid discharging head improved in heat dissipation property includes a rectangular recording element substrate having electrothermal transducers generating thermal energy for discharging liquid, first electrodes for supplying electrical signals to the electrothermal transducers, and second electrodes not used for supplying electrical signals to the electrothermal transducers, and a wiring sheet having an opening through which the recording element substrate is exposed, the wiring sheet being provided with a first wiring pattern electrically connected to the first electrodes and a second wiring pattern connected to the second electrodes. A plurality of the first electrodes are formed along a first side of the recording element substrate having a predetermined length and a plurality of the second electrodes are formed along a second side of the recording element substrate, the second side being longer than the first side and extending in a direction transverse to the first side.

Title
