发明名称 LIQUID JET HEAD AND LIQUID JET APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a liquid jet head and a liquid jet apparatus in which a piezoelectric element is driven efficiently. <P>SOLUTION: The liquid jet head includes a pressure generation element 300 having a first electrode 60 provided on one side of a channel formation substrate 10 correspondingly to a pressure generation chamber 12, a piezoelectric layer 70 provided on the first electrode, and a second electrode 80 provided on the piezoelectric layer; a lead electrode 90 provided individually for each pressure generation element 300 and connected electrically to the first electrode 60; and a conductive layer 81 provided in partial contact with the first electrode 60 in a region where the second electrode 80 is not formed, the piezoelectric layer 70 is exposed, and further the first electrode 60 is exposed partially. The lead electrode 90 is connected with the first electrode 60 via a conductive layer 81. <P>COPYRIGHT: (C)2013,JPO&INPIT
