1. A button device for an electronic device, comprising:
a frame part including a conductive material;
a button part movably coupled to the frame part;
an inner conductive part which is disposed in the button part to be moved with the button part and receives electrostatic energy caused by an electrostatic capacitance of the frame part;
a support part coupled to the frame part to elastically support the button part; and
an adhesive conductive part which is coupled to the frame part, is bonded to a touch panel unit, and comes into contact with the inner conductive part to transfer the electrostatic energy of the inner conductive part to the touch panel unit when the button part moves;
wherein the adhesive conductive part includes:
an adhesive base part bonded to the touch panel unit; and
one or more conductive members which are coupled to the adhesive base part to be in contact with the touch panel unit and come into contact with the inner conductive part to transfer the electrostatic energy of the inner conductive part to the touch panel unit when the button part moves.
