    摘要： An ultrasonic sensor includes a vibration plate, a first electrode, a piezoelectric body, and a second electrode. The first electrode is laminated on the vibration plate, that has a length along a surface of the vibration plate in a first direction, and that has a width Wbe along the surface of the vibration plate in a second direction that is orthogonal to the first direction. The width Wbe is not more than the length. The piezoelectric body is laminated on the first electrode and has a width Wpz in the second direction. The second electrode is laminated on the piezoelectric body. A ratio Wbe/Wpz between the width Wbe of the first electrode and the width Wpz of the piezoelectric body is not less than 0.1 and not more than 0.8.

    摘要： A liquid ejecting head includes a flow channel forming substrate having pressure generation chambers communicating with a nozzle opening and arranged in parallel along a lateral direction. A piezoelectric element is provided on one surface of the flow channel forming substrate in correspondence to the pressure generation chamber, and has a first electrode, a piezoelectric layer provided on the first electrode and a second electrode provided on the piezoelectric layer. In a direction intersecting with the arrangement direction of the pressure generation chambers, in boundaries between an active section that is a substantial driving section and an inactive section that is not a substantial driving section of the piezoelectric layer, the first electrode includes a taper section of which a width is gradually decreased toward the boundary from the active section side.
