Provided is an electrostatic transducer capable of reducing thickness and enhancing detection precision or operation precision. An electrostatic transducer (1) includes an insulating sheet (11), a first electrode sheet (12) arranged on the front surface side of the insulating sheet (11) and having a plurality of first through holes (12a) penetrating in a thickness direction, and a second electrode sheet (13) arranged on the back surface side of the insulating sheet (11) and having no through holes in the thickness direction or having a plurality of second through holes (13a) which have a smaller aperture ratio than the plurality of first through holes (12a).
