A keyboard includes a bottom plate and keyswitch devices. Each keyswitch device includes a keycap, a first supporting member, and a second supporting member. The keycap is over the bottom plate. The first and second supporting members are connected between the bottom plate and the keycap and respectively include first and second magnetic attraction portions. The second magnetic attraction portion is configured to attract the first magnetic attraction portion. The first and second magnetic attraction portions respectively have first and second abutting surfaces. When the first abutting surface abuts against the second abutting surface, the keycap is at a highest position relative to the bottom plate. When the keycap moves toward the bottom plate from the highest position, the first abutting surface is at least partially separated from the second abutting surface.
