ABSTRACT:
A key with binding structure includes an elastic key body and a membrane board bound to each other by an adhesive. The elastic key body has an operation portion extending upward there-from for being accessible and a supporting portion protruding downward there-from. A loop groove is defined in a bottom surface of the supporting portion. The membrane board has a top surface from which a projecting wall is projected. The projecting wall is wedged into the loop groove. In assembling, the loop groove absorbs the superfluous adhesive, thereby preventing the adhesive from overflowing. The engagement between the projecting wall and the loop groove performs positioning of the elastic key body and a membrane board, so a fixture for location is not needed in assembling.
