Abstract
A liquid discharge head that records by discharging recording liquid is provided with polymer having a first portion with lyophilic group for lyophilic processing on a partial surface formed at least on a part of the inner face having recording liquid internally filled to be in contact therewith, and a second portion with a group having substantially the same or the same interfacial energy as the surface energy of the partial surface but different from the interfacial energy of the lyophilic group, while the second portion being orientated toward the partial surface, and the first portion being orientated in the direction different from the partial surface. With the structure thus arranged, the surface energy of the inner face of the liquid discharge head is essentially uniformalized, hence preventing air accumulation from being generated in the portion having lower surface energy.
