More Information
Summary:An ink-jet head includes a nozzle which discharges an ink drop to a recording medium. A discharging chamber communicates with the nozzle and contains ink therein. An oscillation plate is provided on a first substrate of silicon, the oscillation plate defining a bottom surface of the discharging chamber, the oscillation plate pressurizing the ink in the discharging chamber when the oscillation plate is actuated. An electrode is provided on a second substrate of silicon, the electrode facing the oscillation plate via a gap between the oscillation plate and the electrode. In the ink-jet head, at least one of a first bonding area of the first substrate and a second bonding area of the second substrate is provided with a silicon oxide film, and the silicon oxide film contains boron on a surface thereof where the first substrate and the second substrate are bonded together.
