The embodiments of this application provide a keyboard, including a keyboard base and a key, and the key includes a keycap and a key holder, where the keyboard further includes a driving portion, and the driving portion includes a driving board, a first mating member, and a second mating member, where the first mating member and the second mating member are arranged on the driving board; the driving board moves in a first direction relative to the keyboard base through the second mating member; and the key includes a key mating member, and when moving in the first direction, the driving board drives the first mating member to move relative to the key mating member to drive the key to descend. The driving portion drives the key to descend, so that the height of the keyboard can be designed to be smaller, and when the keyboard is applied to the electronic device, the thickness of the electronic device can be reduced. For a single keyboard product, the reduced height of the keyboard also facilitates stacking during processing and transportation, thereby saving space.
