An illuminated touch key uses a chamfer structure of a light guide panel disposed on a sensing module or a light guide panel adjacent to a sensing module to guide light emitted by a light source to a hollow area of a keycap to emit light, thereby forming an illuminated pattern corresponding to the hollow area. Accordingly, a user can accurately find the location of the illuminated touch key according to the illuminated pattern. Since there is no need to add a light guide structure above the sensing module, the height of the illuminated touch key will not be increased, such that it is conductive to make the illuminated touch key thinner.
