INK-JET HEAD

摘要

An ink-jet head which is used in an ink-jet recorder and has outlets provided at high density. The head comprises ink outlets, a pressure chamber communicating with the ink outlets, and a piezoelectric vibrating section which includes a piezoelectric film containing Pb, Ti and Zr and electrodes provided on both sides of the piezoelectric film, and is installed in a part of the pressure chamber. The piezoelectric film consists of a 1st layer and a 2nd layer which have the Perovskite structures respectively and are in contact with each other. The 1st layer does not contain Zr or contains Zr with a content less than the content of Zr in the 2nd layer.
