A liquid discharge head which comprises an element substrate having on one surface thereof energy generating element for generating energy to be utilized for discharging liquid from a liquid discharge port, and a liquid supply port communicated with the liquid discharge port, a printed substrate provided with an external fetch electrode, and an IC component for control use for the energy generating element having provided therefor an output side electrode connected with the energy generating element and an input side electrode connected with the external fetch electrode. For this liquid discharge head, at least the aforesaid output side electrode of the IC component for control use is provided for the one surface of the element substrate. With the structure thus arranged, it is made easier to elongate the liquid discharge head in higher precision, and also, as compared with the case where the driver (driving element) for the discharge energy generating element is incorporated on the assembling substrate, the nondefective ratio of the finished products thereof is enhanced, hence contributing to the manufacture at lower costs.
