ABSTRACT:
A keypad of a portable wireless terminal includes a sheet having a plurality of holes, a plurality of keys inserted into respective ones of the holes, and a silicon adhesive layer on a lower surface of the sheet to fix the keys to the sheet. A protrusion at a lower surface thereof contacts a dome switch. The keys are firmly mounted at a precise position, and more beautiful design can be realized since a decoration line or a decoration shape can be easily formed to set an appearance of the keys.
