ABSTRACT:
A water-repellent film that is formed on a solid substrate includes: a molecule (A) including at least one or more of siloxane bonding (—Si—O—) at both ends and a hydrocarbon chain in a middle part; and a molecule (B) including a fluorocarbon chain at one end and at least one or more of siloxane bonding (—Si—O—) at another end, wherein a polymer film is formed at least with the molecule (A) and the molecule (B). This polymer film forms a covalent bond with a surface of the substrate via siloxane bonding (—Si—O—), and the surface thereof is covered with fluorocarbon chains having high water repellency. Therefore, this film prevents the intrusion of alkali ions. Thereby, an ink jet head and an ink jet type apparatus having a water-repellent film that is not destroyed by the long-term contact with alkaline ink can be provided.
