Abstract: An electromechanical transducer element includes a first electrode, a second electrode, and a piezoelectric material. The piezoelectric material is disposed between the first electrode and the second electrode and deformable with a voltage applied in accordance with a drive signal. The piezoelectric material is made of a composite oxide having a perovskite structure preferentially oriented in at least one of a (100) plane and a (001) plane. A drop in diffraction intensity is included in a rocking curve corresponding to at least one of a (200) plane and a (002) plane measured at a position of 2θ where the diffraction intensity is largest at a peak of diffraction intensity corresponding to the (200) plane out of peaks of diffraction intensity measured by an X-ray diffraction 0-20 method.

Abstract: A flow path forming substrate has a pressure generation chamber communicating with a nozzle opening; and a communication plate having a supply path communicating with a manifold common to and communicating with the pressure generation chamber. A recess of the manifold opens opposite to the flow path forming substrate. The recess has a first recess, and a second recess deeper than the first recess. Supply paths are open on a bottom surface of the first recess, and are arranged in a first direction between the first and second recesses. An inclined surface inclined toward the bottom surface of the second recess from the bottom surface of the first recess is provided along the first direction. The inclined surface is configured as alternately repeated first and second inclined surfaces with different angles. A pitch of adjacent second inclined surfaces is smaller than a pitch of adjacent supply paths.

Abstract: An electronic device includes a capacitor that is configured with a first electrode layer, an insulating layer, and a second electrode layer being formed in the order listed herein. At least one end of the capacitor is defined by an end of the second electrode layer. The insulating layer is provided so as to extend to a non-element region that is on the outside of one end of the capacitor. The insulating layer under the non-element region is formed thinner than the insulating layer under the capacitor. A difference between the thickness of the insulating layer under the non-element region and the thickness of the insulating layer under the capacitor is equal to or less than 50 nm.
