A liquid discharge head includes: a substrate including an element that generates energy to discharge liquid and a liquid supply port; a flow path forming member on the substrate which forms a space therebetween with the substrate and has a discharge port therein, the space constituting a pressure chamber, and a flow path causing the pressure chamber and the liquid supply port to communicate; an interlayer provided between the substrate and the flow path forming member; and a protection layer including metal for protection, wherein the interlayer is disposed so as to avoid a first region corresponding to the element, a second region corresponding to a region of the flow path on a pressure chamber side, and a portion corresponding to a boundary between the first region and the second region, and wherein at least apart of the portion is covered with the protection layer.
