Patent attributes
A piezoelectric actuator includes a channel unit having a manifold and pressure chambers; a vibration plate covering the pressure chambers and the manifold; a piezoelectric layer formed on an upper surface of the vibration plate; individual electrodes formed on an upper surface of the piezoelectric layer; and contact points each drawn on the upper surface of the piezoelectric layer from one of the individual electrodes up to an area facing the manifold. Supporting sections, contacting with a surface of the vibration plate and extended from the inner surface of the manifold, is formed at areas of the channel unit each overlapping with a tip of one of the contact points. Accordingly, sufficient pressure to the contact points can be exerted upon connecting the piezoelectric actuator and a wiring member. A liquid transporting apparatus having a high reliability of electrical connections can be provided.
