ABSTRACT:
An ink jet recording head includes a piezoelectric element with an outer cross-sectional shape having opposed, first surfaces and opposed second sufaces. An electric field applied to a piezoelectric element on one of the surfaces is stronger in one direction than another, thereby increasing the discharge efficiency of the ink jet head.
