Abstract
The present invention provides a technology for decreasing a dispersion of the performance among electromechanical transducers each having through wiring. A method for manufacturing an electromechanical transducer includes: obtaining a structure in which an insulative portion having a through hole therein is bonded onto an electroconductive substrate; filling the through hole with an electroconductive material to form a through wiring which is electrically connected with the electroconductive substrate; and using the electroconductive substrate as a first electrode, forming a plurality of vibrating membrane portions including a second electrode, which opposes to the first electrode through a plurality of gaps, on an opposite side of the first electrode to the side having the insulative portion, to thereby forming a plurality of cells.
