Dielectric member, piezoelectric member, ink jet head, ink jet recording apparatus, and production methods thereof

摘要

A dielectric member including, on a substrate (5), a lower electrode, an oriented dielectric layer (7), and an upper electrode (8), in which at least either of the electrodes has an at least two-layered structure (31,32) constituted of perovskite type oxide conductive layers, and has an orientation.
