PROBLEM TO BE SOLVED: To provide a movable contact body with an illumination function suppressed in the leakage of light and excellent in illumination quality. SOLUTION: A light guide sheet 21 is superimposed over an base sheet 1 which adhesion-holds a movable contact body 3 by an adhesive agent 2 at a lower side, when the light guide sheet 21 is mounted to a circuit board 11, its size is designed to cover cutouts 1A of the base sheet 1 arranged at positions corresponding to mounting positions of a light emitting element 14, slits 22 with prescribed lengths and no space at the cutouts are arranged at positions of the light guide sheet 21 corresponding to an inner position of the cutouts 1A, an upper part of the light emitting element 14 is covered with an edge outside the slits 22 of the light guide sheets 21, and the cut face on the inner side of the slit 22 is made to be an incident part 21B from the light emitting element 14.
