PURPOSE: A plug assembly is provided to prevent a wire connected to terminals and to increase sound transmission performance by removing noise. CONSTITUTION: An electrode terminal is connected to the wire. A ground terminal(33) is closely located in an electrode terminal circumference direction. An insulator(20) insulates interval between an electrode terminal and a ground terminal. A stopper(43) is projected to the circumference direction of an insulator. The stopper is supported in the ground terminal. The stopper prevents the rotation of the electrode terminals.
