The invention provides a key. The key comprises a protective cover and a key cap. The key cap is provided with a diversion shoulder surface. When the protective cover and the key cap are adhered and combined with each other by using the adhesive, the overflowed excessive adhesive can be retained on the flow guide shoulder surface, so that the excessive adhesive is prevented from being diffused to other areas. 本发明提供一按键，按键包括一防护盖以及一键帽。键帽具有一导流肩面。当防护盖与键帽使用黏胶彼此黏贴结合时，溢出的多余黏胶可以留置于导流肩面，避免多余的黏胶扩散至其他区域。
