PROBLEM TO BE SOLVED: To provide an input device capable of making touch typing operation possible to enhance operability and miniaturizing the whole device. SOLUTION: The input device is equipped with central switch element parts 2, 4 driven through a central pushing operation part 7, and peripheral switch element parts 3, 5 facing on both sides of the central switch element parts 2, 4 and driven through a peripheral pushing operation part 7, the central pushing operation part 7 and the peripheral pushing operation part 8 are integrally formed with a flexible insulating material, the central pushing operation part 7 is protruded in a dome shape to the peripheral pushing operation part 8, and operation feeling in pushing of the central pushing operation part 7 is made different from that of the peripheral pushing operation part 8 by making the pushing operation amount of the central pushing operation part 7 larger than that of the peripheral pushing operation part 8.
