Abstract
A keycap structure includes a reinforcement element and a keycap body. The reinforcement element includes two long segments and two short segments. The keycap body includes plural fixing parts and two protruding parts. The plural fixing parts are used for fixing two ends of each long segment of the reinforcement element. The two protruding parts are used for pushing the two short segments of the reinforcement element, so that the reinforcement element is subjected to deformation. Consequently, the reinforcement element generates a reacting force to push against the bilateral sides of the keycap body. Under this circumstance, the top surface of the keycap body is formed as a downwardly-concave arc-shaped surface, so that the shape of the keycap structure is effectively corrected.
