1. An electrostatic transducer, comprising:
an insulator sheet;
a first electrode sheet, disposed on a first surface of the insulator sheet;
a lead, comprising a core wire and a coating formed of a thermoplastic material and coating the core wire, the lead having a portion disposed overlapping the first surface of the insulator sheet and a portion disposed overlapping the first electrode sheet;
a first bonding part, electrically bonding the first electrode sheet with the core wire of the lead in a first area in a plane direction of the insulator sheet, wherein the first electrode sheet and the core wire of the lead are disposed overlapping each other in the first area; and
a second bonding part, bonding the insulator sheet with the coating of the lead in a second area in the plane direction of the insulator sheet that is different from the first area, wherein the insulator sheet and the coating of the lead are disposed overlapping each other in the second area.
