A one-hand keyboard is provided to maximize a working efficiency by enabling a user to use the keyboard with one hand while using a mouse with another hand, as the size of the keyboard is reduced by overlapping a part of keys. A one-hand keyboard includes all keys of a usual keyboard. The infrequently used keys are arranged to be used by using a secondary key(2), and a usual key arrangement of Hangul and alphabet which is familiar to the user is kept without any change in the one-hand keyboard.
