Abstract
A liquid recording head includes a protective layer having resistance to liquid and an adhesiveness improving film disposed on a second surface of a silicon substrate, opposite to a first surface. The first surface and the second surface have a plane direction (100). The protective layer is disposed in a peripheral region of an opening of a liquid supply port. A liquid ejection chip is bonded to a head substrate with an adhesive so that the liquid supply port communicates with a liquid introduction port on a side of the second surface of the silicon substrate.
