Abstract
(EN)
Provided is an electrostatic transducer which has a reduced film thickness and offers increased detection accuracy or operation accuracy. The electrostatic transducer (1) is provided with: an insulator sheet (11); a first electrode sheet (12) which is disposed on a front surface side of the insulator sheet (11) and has a plurality of first through-holes (12a) penetrating through the first electrode sheet (12) in a thickness direction thereof; and a second electrode sheet (13) which is disposed on a back surface side of the insulator sheet (11), wherein the second electrode sheet (13) either has no through-holes in the thickness direction thereof or has a plurality of second through-holes (13a) having an opening ratio smaller than that of the plurality of first through-holes (12a).
