<P>PROBLEM TO BE SOLVED: To provide a liquid droplet ejecting head and liquid droplet ejecting apparatus whose durability has improved. <P>SOLUTION: A liquid ejecting head includes: a pressure chamber substrate 10 where a plurality of pressure chambers 11 that communicates with nozzle holes 21 are provided respectively; and a piezoelectric element 100 including a first conductive layer 40, a piezoelectric material layer 50, and a second conductive layer 60 provided in order on the pressure chamber substrate 10, and has an overlap area 143 where the pressure chamber 11, the first conductive layer 40, the piezoelectric material layer 50, and the second conductive layer 60 are overlapped. The second conductive layers 60 is continuously provided overlapping the plurality of the pressure chambers 11. The first conductive layer 40 which makes, in the overlap area 143, a first direction 210 as a longitudinal direction and a second direction 220 which intersects perpendicularly with the first direction 210 as a shorthand direction, is provided in each overlap area 143 and has an end part area 141 at the end side of at least one side of the overlap area in the first direction 210. The width of the end part area 141 gets narrow in the second direction 220 as it goes toward the end of the first direction 210. <P>COPYRIGHT: (C)2012,JPO&INPIT |
