Description
かかる第1の態様では、圧電体層の電気抵抗率を所定の値にすることで、耐電圧を向上することができると共に、耐久寿命を長くすることができる。
また、所定の添加物を添加することで、所望の電気抵抗率及び耐電圧の圧電素子を得ることができると共に、耐久寿命を長くして信頼性を向上することができる。
さらに、圧電体層のリーク電流を所定の値にすることで、耐久寿命を長くすることができ、信頼性を向上することができる。
また、圧電体層の抗電界及び残留分極強度を規定することで、圧電体層の結晶性がより優れたものとなり、圧電素子の変位特性及び耐久寿命がさらに向上する。
また、圧電体層の耐電圧を所定の値にすることで、耐久寿命を長くすることができ、信頼性を向上することができる。
かかる第2の態様では、圧電体層の結晶性が大幅に向上する。したがって、変位特性に優れると共に、耐電圧が高く耐久寿命の長い圧電素子を提供することができる。
かかる第3の態様では、耐久寿命を向上して信頼性を向上した液体噴射ヘッドを得ることができる。
かかる第4の態様では、耐久寿命を向上して信頼性を向上した液体噴射装置を得ることができる。
