Abstract
To provide an ink-jet head substrate enabling both highly koge. characteristic ink and corrosive ink to be used, an ink-jet head using the same basis and an ink-jet recording apparatus equipped with the same head. The ink-jet head substrate includes: heat generating resistors forming heat generating sections on a base; electrode wires electrically connected to the heat generating resistors; and anti-cavitation films installed via an insulator protective layer on the heat generating resistors and the electrode wires, in which the anti-cavitation film is formed of materials varying with individual given areas on the base.
