Abstract:
1. An electromechanical transducer device comprising: a substrate that is conductive; and a plurality of electromechanical transducer elements disposed on a first surface of the substrate, each of the plurality of electromechanical transducer elements comprising: wherein a groove that electrically isolates the plurality of electromechanical transducer elements from each other is formed in the substrate, the groove extending from a second surface of the substrate toward the first surface of the substrate and extending directly and entirely onto the first electrode, the second surface being opposite the first surface, wherein an opening of the groove formed on the first surface of the substrate and the supporting unit overlap with each other, wherein the opening of the groove formed on the first surface of the substrate and the cavity do not overlap with each other, and wherein a width of the groove on the first surface of the substrate is smaller than a width of the groove on the second surface of the substrate.
