Abstract:
A liquid discharge head configured to discharge liquid is disclosed that includes a silicone resin layer formed on the side of a surface from which the liquid is discharged. The silicone resin layer serves as a water-repellent layer. The number of water-repellent molecular chains is greater than or equal to half of the number of hydrophilic molecular chains on the surface of the silicone resin layer, and the number of hydrophilic molecular chains in the silicone resin layer is greater on the side of the interface with a base material on which the silicone resin layer is formed than on the surface of the silicone resin layer.
