It comprises a touch panel with a plurality of band-like optically transmissive lower electrodes and upper electrodes formed at predetermined intervals in directions perpendicular to each other on an upper surface of an optically transparent base sheet, a dome-like movable contact formed from a conductive metal sheet which is mounted under the touch panel, and a light guide sheet with a plurality of convex-concave light emitting portions formed on an optically transparent substrate, which is disposed between the touch panel and the movable contact. Accordingly, uniform illumination can be attained by using only one or two light emitting elements, and it is possible to obtain a movable contact body capable of inexpensive and reliable illumination.
