Abstract:
1. An electromechanical transducer, comprising: multiple elements each comprising at least one cell, each of the elements including: a first electrode, and a second electrode opposed to a first face of the first electrode so as to interpose a cavity between the first electrode and the second electrode, wherein the first electrode comprises a conductive substrate that is divided for each of the elements by grooves extending from the first face to a second face which is opposite from the first face; and insulating films formed on opposing side walls of the conductive substrate and defining each of the grooves, wherein a width of each of the grooves is narrower on the second face side of the conductive substrate than on the first face side of the conductive substrate, and wherein the cavity and the grooves are not connected to each other.
