Ink jet printing head for improving resolution and decreasing crosstalk |
摘要 |
An ink-jet printing head comprises: a pressurizing chamber substrate having first and second sides opposing each other; a plurality of pressurizing chambers formed on the first side of the pressurizing chamber substrate; channels formed on the second side of the pressuring chamber substrate to be opposite to the pressuring chambers, respectively; oscillating plate films for pressurizing ink within the respective pressurizing chambers; and piezoelectric thin-film elements, each having upper and lower electrodes and a piezoelectric film sandwiched between the upper and lower electrodes, the piezoelectric thin-film being formed in the channel, wherein at least the upper electrode is formed to have a narrower width than that of the pressurizing chamber. And a method for producing the ink-jet head.
