Abstract:
A liquid discharge head includes a recording element substrate including energy generating elements configured to generate energy for discharging liquid and a driving circuit configured to drive the energy generating elements, and a wiring unit including a plurality of connection terminals for connection with the main body side and electrically connected to the recording element substrate. In the wiring unit, wiring lines are respectively connected to the plurality of connection terminals, and a functional element configured to regulate an applied voltage to a predetermined voltage or less is provided between at least one signal wiring line connected to the driving circuit and used to transmit a signal for driving the energy generating element among the wiring lines and the wiring line having a relatively larger electric capacitance than that of the signal wiring line.
