Abstract
An ink-jet recording head includes: a substrate having a first main surface and a second main surface; ink cavity chambers formed on the second main surface of the substrate; and a piezoelectric element device formed on the first main surface of the substrate, the piezoelectric element including a first electrode, a piezoelectric thin film and a second electrode stacked in this order. A material of the first electrode is the same as that of the second electrode in electrochemical potential.
