发明名称 Liquid transporting apparatus and piezoelectric actuator
摘要 A liquid transporting apparatus includes a piezoelectric actuator which applies a pressure to liquid in a pressure chamber and which has a vibration plate covering the pressure chamber; a piezoelectric layer formed on a surface, of the vibration plate, not facing the pressure chamber; an electrode formed on a surface of the piezoelectric layer not facing the vibration plate at a portion facing the pressure chamber; a contact point formed on the surface of the piezoelectric layer not facing the vibration plate; and a connecting portion formed on the surface of the piezoelectric layer not facing the vibration plate and connecting the electrode and the contact point; and the connecting portion extends from the contact point and is connected to a portion, of the electrode, which is different from a nearest portion nearest to the contact point.
