Abstract:
1. An electromechanical transducer, comprising multiple elements each comprising at least one cellular structure, the cellular structure comprising: a silicon substrate; a monocrystalline silicon diaphragm; and a supporting portion, for supporting the monocrystalline silicon diaphragm so that a gap is formed between a first surface of the silicon substrate and the monocrystalline silicon diaphragm, wherein the silicon substrate is configured to be a common electrode which is electrically connected between the multiple elements, wherein the multiple elements are electrically separated from one another by a separation of a membrane including the monocrystalline silicon diaphragm for each of the multiple elements, and wherein each of the multiple elements comprises, in a through hole passing through a first insulating layer including the supporting portion and the silicon substrate:
