ELECTROSTATIC TRANSDUCER AND ELECTROSTATIC TRANSDUCER UNIT

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