Description
かかる第1の態様では、下電極をヤング率が200GPa以上の高硬度とすることで、圧電素子を繰り返し駆動することによって、下電極の展性が失われて塑性変形することなく、圧電素子の変位低下を防止することができる。
かかる第2の態様では、下電極として、白金、酸素及びその他の金属の合金を用いることで、所望の硬度の下電極とすることができると共に、優れた導電性を保持させることができる。
かかる第3の態様では、下電極に用いる合金の白金とチタンとの比を規定することで、所望の硬度を得ることができる。
かかる第4の態様では、下電極に用いる合金の白金と鉛との比を規定することで、所望の硬度を得ることができる。
かかる第5の態様では、下電極に所定の金属を用いることで、所望の硬度の下電極とすることができると共に、優れた導電性を保持させることができる。
かかる第6の態様では、所定硬度の下電極を振動板の一部として機能させることで、圧電素子の優れた変位を維持させることができる。
かかる第7の態様では、優れた変位特性を有する圧電素子を得ることができると共に、圧電素子の高密度化を図ることができる。
かかる第8の態様では、圧電素子の変位低下による液滴の噴射特性の低下を防止して、耐久性及び信頼性を向上した液体噴射ヘッドを実現できる。
かかる第9の態様では、耐久性及び信頼性を向上した液体噴射装置を実現できる。
(実施形態1)
図1は、本発明の実施形態1に係るインクジェット式記録ヘッドの概略構成を示す分解斜視図であり、図2は、インクジェット式記録ヘッドの要部平面図及びそのA−A′断面図である。
以上、本発明の各実施形態について説明したが、本発明の基本的構成は上述した実施形態に限定されるものではない。例えば、上述した実施形態1のインクジェット式記録ヘッドの製造方法では、密着層61としてチタン(Ti)を用いたため、下電極膜60として、密着層61及び白金層62を設けるようにしたが、密着層61としてチタン(Ti)以外の金属、例えば、クロム(Cr)、タンタル(Ta)、ジルコニウム(Zr)及びタングステン(W)等を用いた場合には、密着層61上にチタン(Ti)からなり厚さが5〜50nmの金属層を設けるようにすれば、上述した実施形態1と同様に、下電極膜60のチタンの白金に対する含有率を3〜30%とすることができる。
