1. An electrostatic-type transducer, comprising:
an insulator sheet formed of an elastomer;
a plurality of first electrode sheets which is arranged on a front surface side of the insulator sheet, adhered to the insulator sheet by fusion of the insulator sheet, and arranged with a distance from each other in a surface direction of the insulator sheet; and
one second electrode sheet which is disposed on a back surface side of the insulator sheet, adhered to the insulator sheet by fusion of the insulator sheet, and in which portions facing the plurality of first electrode sheets and portions facing each region between the adjacent first electrode sheets in the surface direction are formed integrally.
