To provide a liquid-repellent member such as a nozzle plate having high
liquid repellency and liquid-repellent durability, a liquid-jet head
using the same, and a liquid-jet apparatus.A liquid-repellent member
includes: an underlayer film which is provided on a surface of a base and
contains silicon; and a liquid-repellent film which is provided on the
underlayer film and is made of a silane coupling agent having a
fluorocarbon group. In the liquid-repellent member, a intensity ratio of
ions highest detected in fluorocarbon-based fragment ions to silicon ions
is greater than or equal to 10 when the fluorocarbon-based fragment ions
and the silicon ions are detected through measurement by a Time-of-Flight
Secondary Ion Mass Spectrometer.
