Abstract
A key structure includes a protective cover and a keycap. The keycap includes flow-guiding bevel surface. When the protective cover and the keycap are adhered on each other through a glue material, an excess portion of the glue material is retained on the flow-guiding bevel surface. Consequently, the excess portion of the glue material will not spread to other regions.
