摘要：
A liquid discharge head includes a liquid discharge head substrate including a discharge port through which a liquid is discharged, and a plurality of energy generating elements that generate energy for discharging the liquid from the discharge port, and a circuit board having flexibility including a pair of differential transmission lines for transmitting differential transmission signals used as logical signals for driving the energy generating elements, to the liquid discharge head substrate, and a voltage supply line for supplying a voltage applied to the energy generating elements to obtain the energy, to the liquid discharge head substrate, wherein the pair of differential transmission lines is provided on one surface of the circuit board, and the voltage supply line is provided on the other surface of the circuit board, which is on a reverse side of the one surface.
