Abstract
A liquid discharge head has a chamber wall member forming a liquid chamber and a discharge head substrate containing a laminate of a base substrate having a surface for an element generating energy for discharging liquid. A first and second layer is formed contacting the wall. The second layer has adhesiveness with the chamber wall member higher than adhesiveness of the first layer, forming the liquid chamber with the chamber wall member. The first layer has a portion exposed from the second layer as viewed from a first direction orthogonal to the surface and contacting the chamber wail member at a position distant from the liquid chamber in a second direction orthogonal to the inner surface of the wall relative to a portion where the wall and second layer contact, and the length in the second direction of the portion of the first layer is 0.3 μm or more.
