Abstract
A liquid discharge head comprises: a discharge element substrate including a discharge port for discharging liquid and a discharge energy generating element; an electrical wiring substrate for inputting an electrical signal to the discharge energy generating element; a supporting mechanism for supporting the discharge element substrate and the electrical wiring substrate; an electrical connection portion for electrically connecting the discharge element substrate with the electrical wiring substrate; a sealant coated on the electrical connection portion; and a film-like member coating the electrical connection portion along the shape of the electrical connection portion through the sealant. Thus, the liquid discharge head resultingly includes the electrical connection portion on which the height of the sealant is suppressed and lowered sufficiently so as to prevent a problem that the electrical connection portion is damaged and/or exposed due to its height.
