摘要

A silent keyboard and a key structure are provided. The key structure includes a keycap, a buffering layer, a stabilizing element and a supporting plate. The keycap includes a bottom surface and a protrusion edge. The protrusion edge is disposed on a periphery of the bottom surface. The buffering layer is disposed on the bottom surface and the protrusion edge. The buffering layer includes a flat part, a raised part and plural coupling parts. The stabilizing element is located under the keycap and pivotally coupled to the coupling parts. The supporting plate is located under the keycap. The supporting plate includes a key seat, a supporting surface and plural recesses. The plural recesses are aligned with the corresponding coupling parts. While the keycap is moved toward the supporting plate, the flat part, the raised part or the plural coupling parts are subjected to deformation.
