<p>PROBLEM TO BE SOLVED: To provide a liquid discharge head which prevents a flow passage wall member from peeling from a substrate.SOLUTION: A liquid discharge head includes a substrate and a flow passage wall member which forms a wall of a flow passage of a liquid on a surface of the substrate. The flow passage wall member is formed of photosensitive resin, and includes a first region and a second region arranged along a parallel direction to the surface of the substrate. Crosslinking density of the first region of the flow passage wall member is lower than crosslinking density of the second region.</p> |
