Abstract
A liquid discharge head comprises an element substrate made of Si having a discharge port for discharging a liquid, an energy generating element for generating an energy for allowing the liquid to be discharged from the discharge port, and a supply port for supplying the liquid to the discharge port and a liquid containing member made of a resin having a communication port communicated with the supply port, in which the element substrate and the liquid containing member are adhered with an adhesive agent. An inorganic film obtained by hardening compositions containing a silica precursor is formed on at least a surface corresponding to a portion of the liquid containing member to which the element substrate is adhered.
