Abstract
Provided is an electromechanical transducer having a reduced unnecessary signal and improved acoustic characteristics. The electromechanical transducer includes an element. The element includes a plurality of cells that are two-dimensionally arranged and electrically connected. Each of the cells includes: a first electrode; and a vibrating film including a second electrode, the second electrode being opposed to the first electrode with a gap interposed therebetween. The cells are arranged so that, when center portions of the plurality of cells are connected by straight lines in all combinations, one of outermost straight lines and another of the outermost straight lines are non-parallel with each other or different in length of parallel portions.
