1. A touch screen-attached button device comprising:
a base fixed to a surface of a touch screen;
a push button overlapping the base, disposed to move vertically with respect to the base, and including a central part and a flange part extending from an outer boundary of the central part in a stepped manner;
a bezel covered on the push button such that the central part is exposed and the flange part is covered and detachably coupled to the base; and
a conductive elastomer made of a conductive elastic material, elastically supporting the push button in an upward direction while interposed between the base and the flange part of the push button, and having a downward protrusion protruding downward toward the touch screen,
wherein a downward protrusion through-hole into which the downward protrusion fits is formed in the base, and
when the push button is pressed downward, the conductive elastomer is pressed downward, and thus the downward protrusion passes through the downward protrusion through-hole and comes into contact with the surface of the touch screen;
wherein the base is provided with a plurality of hooks protruding upward, and
the bezel is provided with a plurality of interference protrusions mutually interfering with the plurality of hooks such that the bezel is not separated from the base when covered on the push button.
