A key input device for a computer is provided to prevent an incorrect operation of the computer such as a mobile terminal by preventing input of surrounding keys when a user presses one of the keys, and realize a wide and thin key input device. An insertion frame(120) is thinner than a button(110), and includes an insertion hole inserted by each button. A key signal generator generates a key signal corresponding to manipulation of the button. A touch transferor(140) is installed between the insertion frame and the key signal generator, is an elastic body bent by downward pressing of the button, and has a flat upper plate attached with the button and the insertion frame. The touch transferor forms a pressing projection, which presses the key signal generator by the downward pressing of the button, at a rear side corresponding to each button, and a bending prevention member preventing other pressing projections from pressing the key signal generator by forming a higher sill than the pressing projection around each pressing projection.
